Digital curation

Digital curation is the active management and preservation of digital data over its entire lifecycle, encompassing activities from planning its creation and initial selection to ongoing maintenance, appraisal, and dissemination to ensure long-term accessibility, authenticity, and usability for current and future needs.^[1] This process addresses the challenges posed by rapidly evolving technologies, formats, and storage media that threaten the obsolescence or loss of digital assets, applying principles of sustainability, interoperability through common standards, and protection against degradation.^[1] In essence, it transforms static digital information into dynamic, reusable resources that support research, cultural heritage, and decision-making across sectors.^[2] The concept of digital curation emerged in the early 2000s, primarily from the scientific and e-science communities grappling with the explosion of digital research data and the need for its reliable long-term stewardship.^[3] A pivotal development was the establishment of the Digital Curation Centre (DCC) in the United Kingdom in 2002, funded by the Joint Information Systems Committee (JISC) to promote best practices in data management and preservation.^[4] This was followed by the launch of the peer-reviewed International Journal of Digital Curation in 2006, which solidified digital curation as a distinct academic and professional discipline focused on holistic data lifecycle approaches rather than mere technical archiving.^[4] Early influences included international standards like the Open Archival Information System (OAIS) reference model, adapted to emphasize proactive curation over reactive preservation.^[2] Central to digital curation is the DCC's Curation Lifecycle Model, a graphical framework that outlines sequential and iterative actions for effective data management, divided into key stages such as ingest (acquisition and validation), preservation planning, and access/dissemination.^[5] This model supports roles across functional units, including appraisal for selection, metadata creation for discoverability, migration to prevent format obsolescence, and quality assurance to maintain data integrity.^[5] It underscores curation's iterative nature, where activities like re-appraisal and transformation occur cyclically to adapt to changing user needs and technological landscapes.^[5] Digital curation's importance spans academia, cultural institutions, government, and industry, where it enables data reuse for innovation, ensures compliance with legal and ethical standards, and safeguards investments in digital content amid growing volumes of born-digital materials.^[4] For instance, in research environments, it facilitates collaboration and reproducibility by enhancing data quality from creation onward, while in heritage sectors, it preserves irreplaceable records like photographs, manuscripts, and multimedia for public access.^[2] Challenges include resource constraints and skill gaps, but ongoing advancements in tools and policies continue to evolve the field toward more robust, automated solutions.^[4]

Overview and History

Definition and Scope

Digital curation is defined as the active management and preservation of digital data over its entire lifecycle to ensure long-term accessibility, usability, and value.^[6] This process encompasses maintaining and enhancing digital materials, mitigating risks such as technological obsolescence, and facilitating their reuse for research and other purposes.^[6] Unlike simple data storage, digital curation requires ongoing human decision-making and intervention to adapt to evolving technological and contextual needs.^[7] Key objectives of digital curation include selection and appraisal to determine which materials warrant preservation, ingestion into secure systems, preservation planning to address potential threats, maintenance to ensure integrity, and dissemination to enable access and reuse.^[5] These activities are guided by models such as the DCC Curation Lifecycle Model, which outlines sequential and cyclical steps from creation through disposal.^[5] The scope of digital curation extends to both born-digital content—originally created in digital form, such as emails, databases, and multimedia files—and digitized materials converted from analog sources, like scanned documents or photographs.^[2] It applies across diverse sectors, including libraries, archives, and museums for institutional collections; research environments for scholarly data; and even personal collections for individual digital memories.^[8]^[9] The term digital curation first appeared in 2001 amid growing initiatives in digital libraries and preservation efforts to address the challenges of managing rapidly proliferating digital information.^[10] This development reflected broader shifts toward proactive strategies for handling digital assets beyond mere archival storage.^[11]

Etymology and Evolution

The term "curation" originates from the Latin verb curare, meaning "to take care of," a concept historically applied to the stewardship and care of physical collections in museums and archives. In the digital realm, this notion adapted during the late 20th century to address the challenges of managing ephemeral electronic data, spurred by the rapid proliferation of digital content after the Internet's mainstream adoption in the 1990s. The specific phrase "digital curation" first appeared in 2001 at a seminar titled "Digital Curation: Digital Archives, Libraries and e-Science," organized by the UK's Digital Preservation Coalition, marking the formal recognition of the discipline as an extension of traditional curation to born-digital materials.^[12]^[13]^[14] Key milestones shaped the field's emergence, beginning with the 1994 Digital Libraries Initiative, a joint program by the U.S. National Science Foundation (NSF), Defense Advanced Research Projects Agency (DARPA), and National Aeronautics and Space Administration (NASA), which allocated $24 million to six projects exploring digital collection building, metadata standards, and user access—laying groundwork for curation practices. In 2004, the Digital Curation Centre (DCC) was founded in the UK through funding from the Joint Information Systems Committee (JISC) and the e-Science Core Programme, aiming to foster research and tools for long-term digital stewardship across disciplines.^[15] The DCC further solidified the terminology in 2005 by defining digital curation as "maintaining and adding value to a trusted body of digital information for current and future use; specifically, the active management and appraisal of data over its entire life cycle," emphasizing proactive intervention beyond mere storage.^[16]^[17]^[18]^[6] Digital curation evolved from foundational principles in archival science and information management, which traditionally focused on physical records, but adapted to the volatile, volume-intensive nature of digital assets post-Internet, incorporating lifecycle approaches to ensure usability and integrity. Early adopters included the Library of Congress, which launched its National Digital Information Infrastructure and Preservation Program in 2000 to curate web archives and multimedia, and JISC, which sponsored pilot projects in the early 2000s to integrate curation into UK higher education research workflows. By the 2010s, the discipline shifted emphasis from static preservation to enabling active reuse and open access, driven by mandates for data sharing in scientific funding and the rise of open science initiatives that prioritized discoverability and interoperability. The field continues to evolve, as evidenced by the International Digital Curation Conference reaching its 19th edition in 2025.^[19]^[20]^[18]^[4]^[21]

Core Principles

Fundamental Principles

Digital curation is grounded in a set of fundamental principles that ensure the long-term integrity, usability, and value of digital assets throughout their lifecycle. These principles guide the active management of data from creation to reuse, emphasizing technical and operational strategies to mitigate risks associated with technological change and data degradation. The principle of provenance requires maintaining comprehensive metadata that documents the origin, custody, and any transformations applied to digital objects. This includes recording the sources of data creation, subsequent handling by custodians, and all preservation actions performed, such as migrations or format conversions. In the OAIS reference model (as updated in the 2024 version, ISO 14721:2024), provenance information forms a core component of Preservation Description Information (PDI), enabling users to verify the historical context and trustworthiness of archived materials. By systematically tracking these details, curators can reconstruct the chain of custody, which is essential for scholarly validation and legal accountability in research data management.^[22] Authenticity in digital curation focuses on preserving the integrity and reliability of digital objects to demonstrate that they remain true to their original form and intent. This is achieved through mechanisms such as checksums for detecting alterations, digital signatures for verifying creator identity, and audit trails that log all access and modification events. The PREMIS metadata standard supports this by defining elements for fixity information, which confirms that content has not been corrupted or intentionally changed without authorization.^[23] Similarly, the OAIS model incorporates fixity as part of PDI to ensure that the semantic meaning and factual accuracy of digital assets are maintained over time. These tools collectively build user confidence in the unaltered state of preserved data, particularly in fields like scientific research where reproducibility depends on verifiable sources.^[24] The principle of persistence addresses the need for strategies that guarantee the long-term viability of digital objects despite evolving hardware, software, and formats. Curators employ techniques like emulation, migration to new formats, and redundant storage to counteract obsolescence and data loss. In digital preservation frameworks, persistence is realized through ongoing monitoring and intervention to reproduce objects accurately in future environments, as outlined in foundational theories that quantify communication across technological shifts.^[25] This principle underscores the shift from mere storage to active management, ensuring that digital assets remain interpretable and functional for designated communities indefinitely.^[26] Accessibility balances the preservation of digital objects with their discoverability and usability for intended users, requiring metadata schemas that facilitate search, retrieval, and interpretation. This involves embedding descriptive, technical, and structural metadata to support user interfaces and tools, while adhering to standards that prevent proprietary lock-in. The OAIS model (as updated in the 2024 version, ISO 14721:2024) defines access rights within PDI to manage permissions and enable controlled dissemination, ensuring equitable availability without compromising security. In practice, this principle promotes the design of systems where users can interact with preserved data in contextually appropriate ways, such as through web-based viewers or APIs.^[23] Interoperability serves as a guiding principle by mandating adherence to open standards and protocols that allow seamless exchange and integration of digital objects across diverse systems. The OAIS reference model (as updated in the 2024 version, ISO 14721:2024) exemplifies this through its functional entities for ingestion, storage, and dissemination, which are designed to be implementable in varied archival environments using non-proprietary formats. By prioritizing standards like those in the PREMIS dictionary, curators ensure that metadata and content can migrate between repositories without loss of functionality, fostering collaboration in global data ecosystems.^[23] The sustainability principle emphasizes cost-effective planning to support ongoing curation activities, including resource allocation for storage, staffing, and technological updates. The Digital Curation Sustainability Model (DCSM) provides a framework for assessing and balancing economic, organizational, and technical factors to maintain viable preservation operations over decades.^[27] This involves strategic decisions on scalable infrastructure and funding models to avoid silos, ensuring that curation efforts remain feasible amid growing data volumes. These principles collectively inform data lifecycle management by providing a foundation for proactive stewardship.

Ethical and Legal Foundations

Digital curation is guided by ethical imperatives that prioritize the protection of intellectual property rights, ensuring creators retain control over their digital works while allowing for preservation and access under defined limits. These rights extend to digital artifacts, where curators must obtain permissions or rely on exceptions to avoid infringement, balancing innovation with fair compensation for original contributions.^[28] Ethical concerns also encompass cultural sensitivity, particularly in curating indigenous or sensitive materials, where digitization risks perpetuating colonial narratives or violating community protocols without consultation.^[29] For instance, tools like Mukurtu software enable Indigenous-led curation to safeguard sacred knowledge from unauthorized dissemination.^[30] Equity in access further underscores these ethics, demanding that digital collections mitigate barriers for underrepresented groups through inclusive metadata and open platforms, preventing the reinforcement of historical exclusions.^[31] Privacy considerations form a cornerstone of ethical digital curation, especially when handling personal data embedded in archives or datasets.^[32] Under the European Union's General Data Protection Regulation (GDPR) of 2018, curators must secure explicit consent for processing identifiable information and implement safeguards like anonymization to prevent re-identification risks. Similarly, the California Consumer Privacy Act (CCPA) of 2018 grants residents rights to access, delete, and opt out of data sales, compelling institutions to audit collections for compliance and restrict access to sensitive elements. These regulations highlight the need for curators to embed privacy-by-design principles, ensuring long-term stewardship does not compromise individual rights.^[32] Legal foundations underpin these practices through frameworks like copyright laws, which govern reproduction and distribution in digital environments. In the United States, the Digital Millennium Copyright Act (DMCA) of 1998 provides safe harbors for curators acting as intermediaries while permitting fair use for non-commercial preservation, such as copying for archival stability without market harm.^[33] Fair use evaluations consider factors like purpose, nature, amount, and effect on the original work's value, enabling limited access for research or education.^[34] Internationally, the WIPO Copyright Treaty of 1996 establishes protections for digital works, requiring adequate safeguards against circumvention while promoting exceptions for libraries and archives. Data protection acts, including GDPR and CCPA, complement these by enforcing accountability in handling personal information across borders. Open access ethics in digital curation emphasize promoting the FAIR principles—Findable, Accessible, Interoperable, and Reusable—to enhance research data sharing without compromising integrity.^[35] These principles advocate for persistent identifiers, rich metadata, standardized formats, and clear licensing to facilitate ethical reuse, as articulated in the 2016 foundational guidelines.^[35] By aligning curation with FAIR, institutions foster transparency and collaboration, though implementation requires vigilance against proprietary restrictions.^[36] Curators face dilemmas in deaccessioning or selective curation, where decisions to remove or prioritize materials risk introducing bias or eroding collection authenticity.^[37] Ethical deaccessioning demands transparent criteria to avoid favoritism toward dominant narratives, ensuring removals serve public trust rather than resource constraints.^[38] Selective practices must counteract inherent biases in source materials, such as underrepresentation of marginalized voices, through diverse appraisal methods.^[39] These challenges relate briefly to broader principles of authenticity, requiring curators to verify provenance amid ethical trade-offs.^[40]

Key Activities and Processes

Data Lifecycle Management

Data lifecycle management in digital curation encompasses the systematic processes to ensure digital assets remain accessible, authentic, and usable over time, from initial creation through long-term preservation. This involves sequential stages that address the evolving needs of data throughout its existence, guided by established models to mitigate risks of loss or degradation.^[5] The pre-curation stage focuses on appraisal and selection, where curators evaluate digital materials based on their informational value, uniqueness, and relevance to organizational goals to determine suitability for long-term retention. This appraisal considers factors such as legal requirements, research potential, and resource implications to prioritize assets for ingestion.^[5]^[41] Following selection, the ingestion stage involves transferring approved data into a curation system, including the assignment of descriptive, technical, and administrative metadata to facilitate discovery, management, and future use. Metadata standards like Dublin Core or PREMIS are commonly applied during this process to embed essential context about the data's origin, structure, and provenance. Repositories such as DSpace and Fedora support these workflows by providing open-source platforms for automated ingestion, validation, and initial storage, ensuring compliance with archival standards.^[5] Active preservation occurs post-ingestion, emphasizing ongoing maintenance to counteract threats to accessibility, such as format obsolescence, through actions like format migration and normalization. This stage ensures data remains interpretable by converting files to sustainable formats while preserving their intellectual content and fixity.^[5] Access and dissemination represent the final active phase, where curated data is made available to users via interfaces that support search, retrieval, and reuse, often with access controls to protect sensitive information. This includes generating dissemination information packages tailored to user needs, balancing openness with security.^[5] Throughout the lifecycle, monitoring for degradation is essential, involving regular integrity checks—such as checksum verification—and risk assessments to detect corruption, hardware failures, or environmental threats. These proactive measures, often automated within repository systems, help maintain data quality and inform preservation actions.^[5]^[42] Disposition concludes the lifecycle by applying criteria for retention or deletion, weighing the data's enduring value against storage costs, legal obligations, and institutional policies. Assets deemed no longer relevant may be securely deleted, while others are retained indefinitely.^[5] Digital curation lifecycle management integrates closely with the Open Archival Information System (OAIS) reference model, an ISO standard that outlines functional entities including submission (for ingest), archival storage (for preservation), and administration (for monitoring and disposition). This alignment ensures robust, interoperable workflows across institutions.

Curation Methodologies

Digital curation methodologies provide structured frameworks and standards to guide the systematic management, preservation, and accessibility of digital assets throughout their lifecycle. These approaches emphasize reliability, sustainability, and adaptability, drawing from established models to address the complexities of long-term digital stewardship. Key methodologies include lifecycle models, audit criteria, metadata standards, cost estimation tools, and iterative processes adapted from other disciplines. The DCC Curation Lifecycle Model, developed in 2008 by the Digital Curation Centre, offers a cyclical framework for planning and implementing curation activities. This model organizes curation into sequential yet iterative stages, encompassing actions such as ingest, appraisal, representation (including metadata creation and description), preservation planning, preservation actions (like migration and validation), packaging, access and use, transformation, and disposition. Its cyclical nature ensures ongoing management, allowing organizations to identify risks, assign roles, and optimize workflows for data creators, curators, and users, thereby supporting holistic research data management infrastructure. The model is adaptable to various granularities and has been widely used for training and resource allocation in digital preservation efforts.^[5]^[43] Complementing lifecycle approaches, the Trustworthy Repositories Audit & Certification (TRAC) framework, published in 2007 by the Center for Research Libraries (CRL) in collaboration with the National Archives and Records Administration (NARA), establishes criteria for evaluating the reliability of digital repositories. TRAC focuses on three core areas: organizational infrastructure (governance, financial sustainability, and policies), digital object management (ingest, metadata handling, and preservation strategies), and infrastructure and security risk management (technical systems, disaster recovery, and security measures). It provides a checklist of 84 criteria, including qualitative and quantitative metrics, to assess a repository's capacity for long-term preservation, enabling audits that build trust among stakeholders such as funders and users. This methodology has influenced subsequent standards like ISO 16363 and is applied in repository self-assessments and third-party certifications.^[44]^[45] PREMIS (Preservation Metadata: Implementation Strategies), maintained by the Library of Congress since 2008 following its initial development by OCLC and RLG in 2005, serves as a standard for capturing and recording metadata essential to preservation actions in digital curation. It defines a core set of implementable elements across four entities—intellectual entities, objects, agents, and rights—covering descriptive, technical, provenance, and rights metadata to document actions like format migrations, fixity checks, and access restrictions. The PREMIS Data Dictionary provides detailed semantics and implementation guidelines, supported by an XML schema for interoperability, ensuring that preservation decisions and processes are traceable and verifiable over time. Widely adopted in repository systems such as Fedora and DSpace, PREMIS facilitates automated preservation workflows and compliance with audit requirements like TRAC.^[23] Cost estimation models, such as Total Cost of Ownership (TCO), are critical for planning and budgeting digital curation efforts, accounting for the full spectrum of expenses beyond initial acquisition. In digital curation contexts, TCO encompasses costs for data capture, storage (hardware and media), maintenance (software updates and staff), and access/dissemination, often calculated over multi-year periods to reflect lifecycle realities. For instance, the Digital Curation Centre's analyses highlight that staff costs typically dominate (around 66% in early 2000s examples), while storage costs have declined dramatically due to technological advances, enabling projections like £1,000 per terabyte per year for sustainable operations. These models support decision-making on automation, shared infrastructure, and economies of scale, helping institutions mitigate financial risks and ensure long-term viability.^[46] Agile curation methods, adapted from software development principles, promote iterative and flexible approaches to digital curation tasks, emphasizing collaboration and responsiveness to evolving needs. Drawing from the Agile Manifesto, these methods prioritize individuals and interactions, usable data over exhaustive documentation, user collaboration, and adaptation to change, applied through sprints for tasks like metadata enhancement or preservation planning. Initial agile data curation principles, proposed in community discussions around 2017, include maximizing data impact via accelerated access, fostering automated interactions through well-documented services, ensuring close creator-curator collaboration, and pursuing incremental improvements with metrics focused on usage and citation. This adaptation enhances efficiency in dynamic environments, such as research data repositories, by enabling self-organizing teams to deliver sustainable enhancements without rigid upfront planning.^[47] Digital Preservation refers to the series of managed activities necessary to ensure the long-term accessibility and usability of digital materials for as long as needed, regardless of changes in technology or environments.^[48] This process focuses primarily on technical strategies such as format migration, emulation, and integrity checks to prevent data loss and degradation, distinguishing it from digital curation's broader emphasis on active management, selection, and value addition throughout the data lifecycle.^[49] Key activities include creating preservation metadata and establishing policies to maintain authenticity and reliability over time.^[50] Digital Stewardship encompasses the comprehensive oversight of digital resources, integrating preservation, curation, and strategic planning to ensure their sustainability and accessibility across their entire lifecycle.^[3] It involves not only technical maintenance but also policy development, funding allocation, and collaboration among stakeholders to address organizational and societal needs for digital assets.^[51] Unlike narrower preservation efforts, stewardship adopts a holistic approach that includes ethical considerations and long-term resource management to support ongoing use and reuse.^[52] Data Archiving involves the long-term storage and preservation of digital data in a repository to ensure its retention and future accessibility, often including activities such as backup, format migration, and metadata management to combat technological obsolescence.^[53] This process emphasizes secure retention and basic retrieval mechanisms, but typically focuses on preservation rather than the dynamic appraisal, selection, or contextual enrichment emphasized in digital curation.^[54] While it requires proactive interventions to maintain integrity, it lacks the full lifecycle management and value-adding aspects of curation.^[55] Digital Asset Management (DAM) is the systematic process of ingesting, storing, organizing, retrieving, and distributing digital files—particularly media such as images, videos, and documents—within a centralized system to support business operations and content reuse.^[56] DAM systems typically incorporate metadata tagging, version control, and workflow tools tailored for commercial environments, enabling efficient asset sharing across teams while maintaining security and rights management.^[57] In contrast to curation's research-oriented focus, DAM prioritizes practical, enterprise-level handling of assets for immediate productivity and marketing purposes.^[58] Born-Digital Materials are digital objects created natively in electronic form without an original analog counterpart, such as emails, web pages, or databases generated directly by software.^[59] These materials often require curation strategies that address volatile formats, embedded dependencies on proprietary systems, and rapid obsolescence risks inherent to their digital-native origins.^[60] Digitized Materials, conversely, are analog items— like photographs or manuscripts—converted into digital formats through scanning or other reformatting processes, resulting in surrogates that aim to replicate physical characteristics.^[61] Curation of digitized content involves ensuring fidelity to the source while managing conversion artifacts and hybrid workflows, differing from born-digital needs by emphasizing migration from physical to digital states.^[62]

Distinctions from Adjacent Fields

Digital curation distinguishes itself from traditional archiving primarily through its proactive, ongoing management of digital materials throughout their lifecycle, in contrast to the more static preservation of physical records in conventional archival practices. Traditional archiving typically involves the appraisal, arrangement, and description of inert paper-based or analog documents once they are transferred to an archival repository, with limited intervention after initial processing.^[63] In digital curation, however, curators actively intervene across the entire records continuum—from creation and selection to long-term maintenance—to address the dynamic nature of digital formats, which can degrade, become obsolete, or require format migration to ensure accessibility.^[63] This approach is necessitated by the inherent instability of digital objects, unlike the relative durability of static physical records.^[63] Compared to digital libraries, digital curation prioritizes the long-term integrity and sustainability of digital assets over immediate user access and retrieval functionalities. Digital libraries focus on organizing and providing current discoverability through search interfaces, metadata standards, and user-oriented platforms to support present-day research and education needs.^[64] In contrast, curation extends beyond access to encompass strategies for mitigating technological risks, such as software obsolescence and data corruption, ensuring that materials remain authentic and usable for future generations, potentially spanning decades or centuries.^[64] This preservation-centric orientation in curation often involves technical interventions like integrity checks and emulation, which are secondary in digital library operations.^[64] Digital curation also diverges from records management by emphasizing the cultural, historical, and research value of digital materials rather than regulatory compliance and operational efficiency. Records management deals with the creation, control, and disposition of records during their active use phase, guided by retention schedules and legal requirements to meet organizational or governmental mandates.^[65] Curation, however, appraises and sustains materials for their enduring scholarly significance, incorporating appraisal decisions that extend beyond compliance to foster reuse and interpretation in broader contexts.^[66] For instance, while records management might dispose of documents post-retention, curation seeks to add value through enhancement and contextual metadata for perpetual access.^[66] In relation to data science, digital curation underscores the long-term stewardship and integrity of datasets, whereas data science centers on analytical processing and insight generation from data. Data science practices often involve cleaning, transforming, and mining data for immediate applications like modeling or visualization, with a focus on short-term utility and algorithmic outputs.^[67] Digital curation, by comparison, maintains data authenticity, provenance, and quality over extended periods to support future reuse, including archiving and governance measures that prevent loss of context during analysis-heavy workflows.^[67] This distinction highlights curation's role in bridging data creation to archival sustainability, rather than prioritizing interpretive or predictive analytics.^[67] Digital curation exhibits interdisciplinary overlaps with information science, drawing on shared principles of metadata management, information retrieval, and knowledge organization, yet it maintains a unique emphasis on the sustainability of digital resources amid evolving technological landscapes. Information science contributes frameworks for data interoperability and user-centered systems, which curation adapts to ensure long-term viability through practices like persistent identifiers and format normalization.^[68] However, curation's distinct focus on environmental and institutional sustainability—addressing challenges such as resource allocation for perpetual access—sets it apart, integrating archival and computational expertise to preserve cultural heritage in digital forms.^[68]

Major Challenges

Data Growth and Volume

The exponential growth of digital data presents one of the most pressing challenges in digital curation, as the sheer volume overwhelms traditional management practices and infrastructure. According to recent IDC forecasts as of May 2025, the global datasphere—the total amount of data created, captured, or replicated—reached 149 zettabytes in 2024 and is projected to expand to 181 zettabytes by the end of 2025, driven primarily by increases in video content, IoT devices, and cloud-based services.^[69] This surge implies escalating storage demands, with curators needing to allocate resources for petabyte-scale repositories that require not only physical hardware but also robust network capacity and computational power to handle ingestion and access.^[42] For instance, institutions like research libraries and national archives must plan for data that doubles roughly every two years, straining budgets and operational workflows.^[70] A key issue arising from this data proliferation is selection overload, where curators face difficulties in appraising and prioritizing vast datasets for long-term preservation amid limited resources. In environments like social media archives, the volume, variety, and velocity of content—such as billions of posts, images, and videos generated daily—complicate traditional appraisal methods that rely on assessing evidential or informational value.^[71] Digital datasets often lack clear boundaries, unlike physical records, making it challenging to determine what merits curation without risking the loss of potentially significant material or incurring unnecessary storage costs.^[70] This overload exacerbates appraisal difficulties, as curators must navigate ephemeral, user-generated content that may hold cultural or historical importance but is buried in terabytes of redundant or low-value data.^[72] The impacts of such growth are profound, including rising operational costs and an urgent need for automated triage tools to filter and prioritize content efficiently. As data volumes increase exponentially, storage expenses—despite declining unit costs—escalate due to the need for redundant, secure systems to mitigate risks like hardware failure, with one analysis noting that storage can represent the largest risk factor in repository operations even as prices drop.^[73] This has led to calls for automated selection techniques to manage scale, as manual processes become untenable for datasets exceeding petabytes. A prominent example is the curation of web archives, where the Internet Archive's Wayback Machine, holding over 99 petabytes of content as of October 2025 with total storage exceeding 200 petabytes, grapples with scaling issues such as slow retrieval times and resource bottlenecks from high traffic and continuous crawling of the expanding web.^[74] These challenges highlight how unchecked data growth can hinder accessibility and preservation efforts without strategic interventions, though standardization efforts may help in coordinating multi-institutional responses.^[75]

Technological Obsolescence

Technological obsolescence poses a significant threat to digital curation by rendering stored data inaccessible due to the rapid evolution of hardware, software, and file formats, potentially leading to permanent loss without proactive intervention. In digital preservation, this risk arises as technologies that were once standard become unsupported, making it impossible to read or interpret data without migration or emulation strategies. For instance, the lifecycle of digital media often spans decades, during which shifts in technology can outpace preservation efforts, emphasizing the need for ongoing monitoring and planning to ensure long-term accessibility. Format evolution exemplifies this challenge, as storage media and file structures have transitioned from physical formats like floppy disks to modern cloud-based systems, necessitating repeated migrations to maintain access. Early floppy disks, such as 8-inch, 5.25-inch, and 3.5-inch variants, became obsolete within years of their introduction due to discontinuation by manufacturers, forcing curators to transfer data to newer media to avoid degradation and incompatibility. Similarly, analog video formats like VHS tapes, popular in the late 20th century, are now at risk of obsolescence as playback equipment becomes scarce and tapes degrade through magnetic decay, prompting migrations to digital formats such as MP4 to preserve content integrity. These shifts highlight how format changes can compound risks, particularly when combined with increasing data volumes that amplify the scale of required interventions. Software dependencies further complicate curation, as proprietary applications essential for viewing or interacting with digital objects may cease support, leading to widespread inaccessibility. A prominent example is Adobe Flash, whose end-of-life on December 31, 2020, affected numerous archived web-based media, including interactive animations and videos, as browsers and operating systems discontinued compatibility, requiring curators to convert Flash content (SWF files) to open standards like HTML5 or WebAssembly. The Smithsonian Institution Archives, for instance, faced challenges in preserving Flash-dependent websites and games, underscoring the vulnerability of software-reliant artifacts to vendor-driven obsolescence. Hardware risks manifest in the need for specialized equipment to access legacy systems, often addressed through emulation to simulate obsolete environments on contemporary hardware. Early personal computers, such as those from the 1980s like the IBM PC, relied on specific processors and peripherals that are no longer manufactured, making direct access to their data or software impractical without emulators that replicate the original system's behavior. Emulation strategies, as outlined by the Council on Library and Information Resources, enable curators to run vintage applications on modern machines by mimicking hardware dependencies, thereby preserving the authentic user experience without physical restoration of rare components. To mitigate these risks, tools like format registries provide essential identification and profiling capabilities for proactive planning. The PRONOM registry, maintained by The National Archives of the United Kingdom, catalogs over 1,300 file formats with details on their technical specifications, risks of obsolescence, and migration pathways, allowing curators to assess and prioritize actions for at-risk holdings. By integrating PRONOM data into workflows, institutions can automate format identification and monitor emerging threats, facilitating timely interventions to sustain access.^[76] A notable case illustrating these issues is NASA's curation of Apollo mission data from the 1970s, where original telemetry tapes stored on 1-inch magnetic reels faced severe decay and obsolescence due to deteriorating media and incompatible playback hardware. The Apollo 11 tapes, intended as backups for mission recordings, were largely erased and reused in the early 1980s amid tape shortages, while surviving reels suffered from binder hydrolysis—a chemical degradation process—rendering much of the raw lunar surface data irrecoverable without extensive restoration efforts. This incident, detailed in NASA's official report, demonstrates the perils of unaddressed technological obsolescence in high-stakes scientific archives, prompting ongoing digitization initiatives to safeguard remaining mission artifacts.

Resource and Labor Constraints

Digital curation efforts are frequently hampered by resource and labor constraints, as the human-intensive nature of tasks such as metadata creation and quality control often exceeds initial projections. Labor represents the largest component of overall curation costs, far surpassing expenditures on hardware, software, or storage. For instance, staff costs in data centers typically account for 69% to 82% of total budgets, highlighting the hidden efforts involved in maintaining data integrity over time.^[77] These activities, including manual metadata generation and validation, demand substantial time and expertise, with automation still limited in addressing the full scope of quality assurance needs.^[4] Skill gaps further exacerbate these challenges, requiring interdisciplinary expertise that combines information technology, archival practices, and domain-specific knowledge. Digital curation professionals must navigate technical skills like data management systems alongside curatorial judgment in areas such as scientific or cultural domains, yet the field suffers from a shortage of trained individuals. According to the U.S. Bureau of Labor Statistics, employment of librarians is projected to grow 2% from 2024 to 2034, slower than the average for all occupations, while archivists, curators, and museum workers are projected to grow 6%, faster than average; however, inadequate training programs and non-standardized job titles hinder workforce development, leading to reliance on generalists ill-equipped for complex curation demands.^[78]^[79] The field continues to face challenges in attracting library and information science graduates to digital curation roles, underscoring the need for targeted education to bridge these gaps.^[80] Funding structures pose additional barriers, with short-term grants ill-suited to the perpetual requirements of long-term preservation. Many projects, including EU initiatives like Europeana, operate on biennial tenders from EU funds and national ministries, providing methodological support for data aggregation but no direct financial aid for ongoing digitization or maintenance.^[81] This mismatch—where funding cycles last 3-5 years while curation demands indefinite stewardship—results in under-resourced operations, as only 21% of researchers receive financial support for archiving despite widespread obligations.^[77] Europeana's model, while promoting sustainability through partnerships and cost reductions in metadata enhancement, leaves cultural institutions bearing the brunt of high digitization expenses, particularly for smaller entities.^[81] In understaffed institutions, the reliance on manual processes amplifies risks of workforce strain and high turnover, as labor shortages compound the demands of increasing data volumes.^[80] Economic models, such as lifecycle costing frameworks developed by the LIFE project, offer tools to predict these expenses by modeling costs across ingestion, storage, access, and preservation phases over 5-10 year horizons. These frameworks enable institutions to forecast total ownership costs, emphasizing the need for proactive budgeting to mitigate perpetual resource shortfalls.

Standardization and Interoperability

Digital curation faces significant challenges due to the absence of universally adopted global standards, which leads to inconsistencies in how digital objects are described and managed across institutions. Variations in metadata schemas, such as Dublin Core (DC) and Metadata Object Description Schema (MODS), exemplify this issue; DC provides a simple set of 15 basic elements suitable for broad resource discovery, while MODS offers a more structured and richer framework with 20 elements and subelements that inherit MARC semantics for detailed bibliographic control, making direct interoperability difficult without mapping or transformation.^[82] These differences arise because DC lacks substructure and precise instructions for elements like "Creator" or "Date," resulting in inconsistent local implementations, whereas MODS addresses complex digital objects but requires greater expertise, hindering seamless adoption in diverse curation environments.^[82]^[83] Interoperability barriers further complicate digital curation, as siloed systems—often using incompatible formats, protocols, or metadata—prevent effective data sharing and reuse across institutional and national boundaries. In digital preservation, these silos manifest in fragmented workflows where repository software like DSpace or Fedora fails to integrate smoothly with institutional systems or distributed services, leading to incomplete preservation chains and reliance on manual interventions.^[84] Such barriers are exacerbated by heterogeneous data structures, including unstructured formats like spreadsheets, which demand advanced semantic mapping to enable cross-system access.^[85] The fluid nature of digital information across temporal and disciplinary lines amplifies these issues, as evolving hardware and software dependencies create ongoing obsolescence risks that vary by context.^[8] Coordination challenges among libraries, governments, and private sectors add to the complexity, with fragmented national digital strategies resulting in disjointed efforts and policy misalignments. For instance, academic libraries often develop isolated digital curation services due to varying institutional priorities, while government initiatives may overlook private-sector innovations, leading to duplicated infrastructure investments without shared protocols.^[86]^[4] Human-centered factors, such as resistance to data sharing stemming from concerns over control or insufficient training, compound these coordination hurdles, necessitating negotiated agreements across distributed networks.^[85] Progress toward standardization has been advanced through key initiatives like the ISO 14721 Open Archival Information System (OAIS) reference model, which provides a conceptual framework for digital archiving that standardizes terminology, processes, and data models to facilitate comparison and integration among systems.^[87] Similarly, the International Internet Preservation Consortium (IIPC) promotes interoperability in web archiving by coordinating global member institutions—spanning over 35 countries—to develop shared tools, training, and collaborative projects that ensure consistent capture and access of born-digital web content.^[88] These interoperability issues contribute to substantial risks, including data silos that foster duplicated curation efforts and the potential loss of collective knowledge through inaccessible or redundant archives. Siloed environments lead to inefficient resource allocation, as organizations replicate similar preservation activities without leveraging shared repositories, ultimately fragmenting the global digital heritage.^[8]^[85]

Digitization of Analog Content

Digitization of analog content involves converting physical materials, such as books, manuscripts, photographs, audio tapes, and three-dimensional artifacts, into digital formats to enable long-term curation and access. This process is essential for preserving deteriorating analog items but presents significant technical hurdles, particularly in achieving high-resolution captures without causing physical damage. For instance, scanning rare books and manuscripts requires specialized equipment like overhead or planetary scanners to capture images at resolutions of 400-600 pixels per inch (ppi) or higher, ensuring fine details are preserved while minimizing handling that could exacerbate fragility. Fragile items, such as brittle paper or tightly bound volumes, demand non-destructive techniques, including the use of cradles or v-support systems to avoid stress on bindings and spines during imaging.^[89] Conservators often assess materials beforehand to identify risks, such as restricted openings in early printed books that could lead to tearing if forced.^[90] Quality control remains a core challenge, encompassing issues like color fidelity and the accuracy of optical character recognition (OCR) for textual content. Maintaining accurate color reproduction requires calibrated scanners with consistent lighting and color targets to match the original hues, as variations in spectral response can distort tonal ranges in digitized images.^[91] For textual materials, OCR performs reliably on printed documents but struggles with handwritten ones, where error rates can exceed 10-15% due to variations in script, ink degradation, and paper texture, necessitating manual verification or advanced handwriting recognition tools to achieve usable accuracy levels above 85%.^[92] These quality concerns are amplified in mass digitization efforts, where inconsistencies can compromise the integrity of the digital surrogate for curation purposes. Scaling digitization to large collections introduces legal and logistical obstacles, exemplified by the Google Books project launched in 2004, which aimed to scan millions of volumes but encountered substantial copyright hurdles from authors and publishers. The initiative faced lawsuits alleging infringement through unauthorized scanning of in-copyright works, leading to a decade-long legal battle resolved in 2015 when a U.S. court ruled the project constituted fair use for search and snippet views, though full access remained restricted.^[93] Beyond legal issues, the sheer volume demands efficient workflows, yet copyright clearances slow progress and limit public availability. Additionally, the process is labor-intensive and costly for complex formats; digitizing audio tapes involves cleaning, winding, and real-time playback to capture analog signals, often taking hours per reel due to degradation risks like sticky-shed syndrome.^[94] Similarly, 3D objects require multiple scans from various angles using structured light or laser technologies, with costs ranging from hundreds to thousands of dollars per item depending on complexity, plus extensive post-processing to align and refine models.^[95] To address these challenges, established best practices emphasize structured workflows, as outlined in the International Federation of Library Associations and Institutions (IFLA) Guidelines for Digitization Projects. These recommend phased planning, including selection criteria, metadata standards, and quality assurance protocols to ensure reproducibility and minimal intervention.^[96] Such guidelines promote the use of open standards for file formats like TIFF for images and WAV for audio, facilitating interoperability while prioritizing preservation over access in initial captures. Post-digitization, the resulting files must be monitored for format obsolescence to sustain curatorial value.

Material and Format-Specific Issues

Digital curation encounters distinct challenges when addressing the preservation of diverse content types, where the inherent properties of materials and formats demand tailored metadata strategies, handling protocols, and technological interventions to mitigate loss of authenticity and accessibility over time. For instance, born-digital artifacts often embed proprietary encodings or interactive elements that complicate long-term viability, requiring curators to balance fidelity to original intent with adaptive preservation techniques. These issues are amplified in emerging formats, where rapid innovation outpaces standardization efforts. In curating manuscripts and digitized texts, a primary concern involves developing robust metadata schemas to capture textual variants, such as editorial revisions or manuscript differences, ensuring scholarly access to historical evolutions without conflating versions.^[97] Handling redactions poses additional hurdles, as curators must systematically identify and mask sensitive information in digital surrogates while preserving the document's structural integrity and contextual annotations for future analysis.^[98] Metadata standards like those from the Getty Research Institute emphasize descriptive and administrative elements to index such variants, facilitating discoverability amid evolving textual scholarship.^[99] For cultural heritage materials, preserving 3D models of artifacts derived from photogrammetry techniques introduces risks of data obsolescence, as proprietary software for rendering point clouds and meshes becomes unsupported, potentially rendering models inaccessible without emulation or migration.^[100] Curators must address format-specific degradation, such as loss of texture fidelity in high-resolution scans, by adopting open standards like glTF to enhance interoperability across platforms.^[101] These challenges underscore the need for proactive validation workflows to verify model accuracy against physical artifacts over decades-long preservation horizons.^[102] Curating intangible cultural heritage, such as performances and oral traditions, relies heavily on video and audio recordings to capture ephemeral expressions, yet preserving the surrounding context—like performer intent, cultural rituals, or linguistic nuances—remains elusive without enriched metadata that documents performative variables.^[103] Institutions employ multimodal approaches, integrating transcripts and ethnographic notes with audiovisual files, to mitigate the flattening of dynamic elements inherent in live traditions.^[104] UNESCO guidelines highlight the importance of community involvement in metadata creation to ensure recordings reflect authentic intangible values rather than isolated artifacts.^[105] Emerging formats exacerbate curation difficulties, particularly for VR/AR content, where immersive environments depend on device-specific runtimes that risk rapid obsolescence, necessitating strategies like scene graph exports to sustain spatial interactions.^[101] Social media ephemera, such as transient posts or stories, challenges preservation due to platform dependencies and privacy restrictions, often requiring API-based harvesting before content vanishes, though legal barriers limit comprehensive capture.^[106] AI-generated media introduces authenticity issues, as algorithmic outputs lack clear provenance, demanding metadata for tracing generative models and input parameters to verify integrity against future deepfake proliferation.^[107] Specific examples illustrate these tensions: preserving interactive web art requires emulating browser environments to maintain user-driven behaviors, as original scripts may fail on modern hardware, with curators employing tools like Webrecorder to archive dynamic states.^[108] Similarly, blockchain-based NFTs face curation obstacles in linking on-chain metadata to off-chain media files, where server downtime or link rot can sever artwork from ownership proofs, prompting hybrid strategies that embed assets directly on distributed ledgers.^[109] These cases highlight the imperative for format-agnostic preservation frameworks to accommodate evolving digital expressions.^[110]

Strategies and Approaches

Technological Solutions

Technological solutions in digital curation encompass a range of software tools, platforms, and systems designed to mitigate challenges such as technological obsolescence and data volume by enabling long-term preservation, automated processing, and secure storage of digital objects. These solutions often align with established standards like the Open Archival Information System (OAIS) model, facilitating the ingest, management, and access of digital content while ensuring its authenticity and usability over time. Key approaches include emulation and migration for rendering obsolete formats, AI-driven automation for metadata enhancement, robust storage infrastructures, monitoring systems for compliance, and innovative tracking mechanisms like blockchain. Emulation recreates the original hardware and software environment to run legacy digital objects, avoiding the need to alter the content itself, while migration converts files to contemporary formats to maintain accessibility. QEMU, an open-source emulator, supports digital preservation by simulating historical operating systems and hardware, allowing curators to execute and view preserved software artifacts without proprietary dependencies. For instance, QEMU has been integrated into preservation workflows to emulate environments for early digital art and documents, demonstrating its reliability in maintaining functional integrity. Complementing emulation, JHOVE (JSTOR/Harvard Object Validation Environment) serves as a Java-based tool for identifying, validating, and characterizing file formats during migration processes, ensuring that converted objects conform to expected standards before archival storage. These tools collectively address obsolescence by providing verifiable pathways to sustain access, with JHOVE's extensibility allowing integration into broader curation pipelines. Automated workflows leverage artificial intelligence and machine learning to streamline metadata generation, reducing manual labor and enhancing discoverability in large-scale digital collections. In image curation, machine learning models apply computer vision techniques to automatically tag visual content with descriptive keywords, such as objects, scenes, or emotions, thereby enriching metadata schemas like Dublin Core without exhaustive human annotation. Scholarly analyses highlight how these AI methods improve curation efficiency in cultural repositories, where automated tagging achieves up to 90% accuracy in controlled datasets, though human oversight remains essential for contextual nuances. Such workflows integrate with existing systems to process heterogeneous data types, supporting scalable curation by generating provenance records and semantic links that facilitate long-term retrieval. Storage solutions prioritize durability, scalability, and cost-effectiveness for archival needs, with cloud-based options like Amazon S3 Glacier offering tiered retrieval classes optimized for infrequently accessed data. S3 Glacier Deep Archive, for example, provides 99.999999999% (11 nines) durability and retrieval times of within 12 hours for standard or up to 48 hours for bulk, making it suitable for preserving petabyte-scale cultural and scientific datasets. Storage costs $0.00099 per GB-month, with retrieval costs as low as $0.0025 per GB for bulk operations (as of November 2025).^[111] Distributed systems like the InterPlanetary File System (IPFS) enable decentralized, content-addressed storage, where files are pinned across peer networks to prevent single points of failure and ensure persistent availability for preservation purposes. IPFS has been adopted in archival projects to maintain verifiable, tamper-resistant copies of digital heritage materials, complementing traditional storage by distributing redundancy globally. Monitoring tools such as Archivematica automate OAIS-compliant processing from ingest to dissemination, incorporating validation, normalization, and packaging into microservices-based workflows. Developed as an open-source system, Archivematica generates preservation metadata (e.g., PREMIS events) and supports format migration, ensuring compliance with standards like ISO 14721 while tracking the lifecycle of digital packages. Institutions use it to monitor integrity through checksum verification and automated reporting, with its modular design allowing customization for specific curation needs. Recent advances in blockchain technology have introduced pilots for provenance tracking, creating immutable ledgers to record the custody and modifications of digital objects post-2020. For instance, projects integrating blockchain with IPFS have demonstrated enhanced traceability in library archives, where hashed records on distributed ledgers verify authenticity and chain of custody without centralized vulnerabilities. A 2023 IEEE study on long-term preservation services piloted blockchain for digital signatures, achieving robust audit trails for archival files by combining it with decentralized storage, thus bolstering trust in curated collections. These initiatives, often tested in cultural heritage contexts, underscore blockchain's potential to automate verification while addressing scalability concerns through hybrid models.

Institutional and Collaborative Strategies

Institutional and collaborative strategies in digital curation emphasize organizational frameworks, partnerships, and capacity-building to ensure long-term sustainability of digital assets. These approaches address resource constraints by fostering coordinated efforts among institutions, governments, and stakeholders to develop policies, share responsibilities, and build expertise.^[1] Policy development forms a cornerstone of these strategies, with national initiatives providing guidelines for systematic curation practices. In the UK, the Joint Information Systems Committee (JISC) funded studies in 2008 to outline models for institutional digital preservation policies, aiming to integrate curation into broader research data management frameworks. These efforts, including the Digital Preservation Policies Study, recommended structured approaches to governance, risk assessment, and compliance to support ongoing digital asset viability across higher education institutions.^[112]^[113] Collaborative consortia exemplify shared infrastructure to distribute curation burdens and enhance scalability. The Data Conservancy, initiated by Johns Hopkins University in partnership with entities like the National Snow and Ice Data Center, offers a discipline-agnostic platform for data collection, preservation, and access, utilizing open-source tools like Fedora Commons to enable interoperable services across research communities.^[114] Similarly, HathiTrust Digital Library, a consortium of over 60 research libraries, maintains a shared preservation repository with more than 19 million digitized volumes (as of 2025), allowing members to contribute content without individual hosting costs while ensuring redundant storage and access for print-disabled users.^[115] These models promote collective development of metadata standards and workflows, reducing redundancy and costs through pooled resources.^[114] Training programs build essential skills for effective curation, often delivered through specialized modules and workshops. The Digital Curation Centre (DCC) provides targeted training on research data management principles, including data management plans via tools like DMPonline, preservation strategies, and FAIR data principles, offered in formats such as one- to two-day workshops for librarians, researchers, and IT professionals.^[116] These sessions, conducted globally since the DCC's inception, emphasize practical application without formal certifications but equip participants to implement institutional policies.^[15] Funding models sustain these initiatives through diversified sources that align with long-term goals. Endowments offer stable support, as seen in philanthropic commitments from foundations like the Bill & Melinda Gates Foundation, which fund data preservation aligned with societal benefits.^[117] Public-private partnerships facilitate innovation, such as industry collaborations providing cloud credits for infrastructure, exemplified by the NIH's BD2K program that supported data reuse platforms before transitioning to member-based models like ELIXIR, where national institutes contribute to maintenance for free global access.^[117] These hybrid approaches mitigate financial risks by blending government grants with private investments.^[117] Audit frameworks enable institutional self-assessment to verify trustworthiness and compliance. The Trustworthy Repositories Audit & Certification (TRAC) criteria, developed in 2007 by the Center for Research Libraries and the National Archives and Records Administration, provide a checklist of over 100 metrics across organizational infrastructure, digital object management, and risk mitigation, allowing repositories to evaluate governance, preservation planning, and technical safeguards internally.^[45] This self-audit tool, aligned with the Open Archival Information System (OAIS) reference model, helps institutions identify gaps and prepare for external certifications like ISO 16363, promoting transparency and accountability in curation practices.^[45]

Emerging Innovations

Artificial intelligence and machine learning are transforming digital curation by enabling predictive analytics for risk assessment and automated appraisal processes. Predictive models analyze historical data on file degradation, format obsolescence, and storage failures to forecast potential threats to digital assets, allowing curators to prioritize interventions proactively. For instance, AI-driven tools can evaluate the long-term viability of datasets by simulating environmental and technological risks, reducing the likelihood of data loss in large-scale repositories.^[118] Automated appraisal leverages machine learning algorithms to classify and select content for preservation, such as the Automated Video Appraisal (AVA) system, which generates preliminary decisions on video recordings that archivists can refine, streamlining workflows in resource-constrained environments.^[119] These innovations enhance efficiency while maintaining curatorial oversight, particularly for born-digital materials where manual review is impractical.^[120] Blockchain and distributed ledger technologies provide immutable audit trails that bolster the authenticity and provenance of curated digital objects. By recording metadata and access events on a decentralized ledger, blockchain ensures tamper-proof documentation of an asset's lifecycle, from creation to reuse, countering risks of alteration or falsification in distributed archives. In library settings, these systems verify the integrity of digital records through cryptographic hashing, enabling verifiable chains of custody without relying on central authorities.^[121] This approach is particularly valuable for preserving cultural heritage, where authenticity underpins scholarly trust and legal validity.^[122] Integrations with open science frameworks, especially the FAIR (Findable, Accessible, Interoperable, Reusable) data principles introduced in 2016, have reshaped curation practices by embedding reusability into ecosystems. Post-2016 implementations emphasize machine-actionable metadata and persistent identifiers to facilitate data discovery and integration across platforms, aligning curation with collaborative research needs. Collaborative networks like the Data Curation Network apply FAIR guidelines to standardize processing, ensuring datasets from diverse sources remain interoperable for long-term analysis.^[35] This shift supports open science by promoting ethical sharing while addressing challenges like metadata inconsistency in heterogeneous collections.^[123] Sustainability innovations in digital curation focus on green computing to minimize the carbon footprint of storage and processing. Practices such as optimizing cloud infrastructures for energy efficiency and employing low-carbon data centers reduce the environmental impact of long-term preservation, where petabyte-scale archives contribute significantly to global emissions. Scalable, on-demand storage models allow curators to deactivate idle resources, cutting energy use by up to 30% in some deployments without compromising accessibility.^[124] These strategies integrate with broader green IT principles, prioritizing renewable energy sources and hardware longevity to align curation with climate goals.^[125] Post-2020 trends highlight curation challenges and solutions for pandemic-related data and emerging metaverse content. During the COVID-19 crisis, digital curators facilitated open repositories like the COVID-19 Open Research Dataset (CORD-19), applying FAIR principles to aggregate and preserve heterogeneous health data for rapid scientific reuse while mitigating misinformation risks.^[126] This effort underscored the need for agile curation in crisis contexts, with practices evolving to include real-time metadata standards for global collaboration. For metaverse content, preservation involves capturing immersive virtual reality assets, such as 3D cultural reconstructions, using blockchain for authenticity and VR-compatible formats for replayability. Platforms like metaverse heritage simulations enable the curation of intangible cultural elements, ensuring their endurance beyond platform lifecycles.^[127] These developments address the ephemerality of virtual environments, fostering sustainable access to interactive digital narratives.^[128]

Applications Across Domains

Cultural Heritage Preservation

Digital curation plays a pivotal role in preserving cultural heritage by ensuring the long-term accessibility and integrity of both tangible artifacts and intangible expressions, mitigating risks from physical decay, geopolitical conflicts, and cultural erasure. Strategies for tangible artifacts often involve advanced digitization techniques such as 3D scanning and virtual reconstructions, which create high-fidelity digital surrogates that can be stored, analyzed, and shared without compromising the originals. For instance, the British Museum employs 3D scanning to digitize its collections, enabling virtual exhibitions and scholarly access to items like ancient sculptures and manuscripts, thereby extending their lifespan beyond physical constraints. These methods not only safeguard against material degradation but also facilitate immersive experiences through technologies like augmented reality. Intangible cultural elements, such as oral histories, traditional performances, and rituals, are preserved through multimedia archiving that captures audio, video, and interactive formats. Digital curation here emphasizes metadata standards and contextual documentation to maintain authenticity and cultural significance, allowing communities to revisit and transmit knowledge across generations. Projects like the Smithsonian Folkways Recordings archive oral traditions from indigenous groups using digital audio preservation, ensuring these ephemeral elements endure despite the absence of physical forms. This approach addresses the ephemerality of living heritage, integrating community involvement to avoid misrepresentation. A prominent case study is UNESCO's Memory of the World Programme, launched in 1992, which focuses on digitizing and nominating documentary heritage of global importance to prevent loss and promote universal access. The program has supported the digitization of diverse collections, including ancient manuscripts from the Middle East and African oral archives, resulting in 570 registered items as of 2025.^[129] Challenges in this domain include ethical considerations around repatriation, where digital surrogates raise questions of ownership and cultural sovereignty; for example, debates over virtual access to repatriated artifacts underscore the need for collaborative agreements between institutions and source communities to respect indigenous rights. Outcomes of these curation efforts have significantly enhanced global access to cultural heritage, democratizing knowledge that was once limited to physical sites. The Europeana portal, aggregating digitized content from European institutions, provides open access to over 58 million items as of 2025, including artworks, books, and audiovisual materials, fostering education and cross-cultural dialogue while adhering to preservation standards.^[130] By addressing repatriation ethics through transparent digital policies, such initiatives not only preserve heritage but also promote equity in its representation.

Scientific and Research Data Management

Digital curation plays a critical role in scientific and research data management by ensuring the long-term accessibility, integrity, and usability of data to support reproducibility, which is essential for validating scientific claims and advancing knowledge. Reproducibility requires curating digital artifacts such as raw data, processed datasets, code, and documentation to allow independent verification of results, addressing challenges like data loss or obsolescence over time. This process involves active management throughout the data lifecycle, including appraisal, metadata creation, and preservation strategies that maintain the context and provenance of research outputs.^[131]^[132] Metadata standards are fundamental to this curation effort, enabling discoverability and interoperability of datasets. For instance, the DataCite Metadata Schema provides a core set of properties, such as identifiers, titles, creators, and resource types, that facilitate accurate citation and persistent linking of datasets to publications. This schema supports DOI minting for datasets, ensuring they can be reliably referenced and retrieved, which is vital for reproducible research across disciplines.^[133]^[134] In particle physics, the CERN Data Preservation in High Energy Physics (DPHEP) collaboration exemplifies these practices by archiving vast volumes of experimental data from accelerators like the Large Hadron Collider, totaling over one exabyte (more than 1,000 petabytes) as of 2025, to enable future analyses and reinterpretations.^[135]^[136]^[137] Similarly, the National Institutes of Health (NIH) has implemented data sharing policies since the 2010s, including the 2014 Genomic Data Sharing Policy and the 2023 Data Management and Sharing Policy, which mandate plans for making scientific data findable, accessible, and reusable to foster collaboration and verification in biomedical research.^[138] Big data in fields like genomics and climate modeling presents unique curation challenges due to volume, velocity, and variety, requiring scalable strategies to handle petabyte-scale datasets while preserving fidelity. In genomics, curating sequences from next-generation sequencing involves managing heterogeneous formats, ensuring quality control against errors, and addressing storage demands that can exceed exabytes, all while complying with privacy regulations. For climate models, challenges include integrating observational data with simulations, correcting biases in historical records, and maintaining version control for evolving model outputs to support accurate projections.^[139]^[140]^[141] Tools like Jupyter notebooks enhance curation by serving as executable research artifacts that bundle code, data, visualizations, and narrative explanations into interactive documents, promoting transparency and ease of reuse. These notebooks allow researchers to document workflows reproducibly, with cells that can be executed in sequence to regenerate results, though curation must address dependencies on evolving software environments to prevent bit rot.^[142]^[143] The impacts of such curation extend to enabling meta-analyses and advancing open science, where shared, well-curated data amplify research efficiency and innovation. Repositories like Dryad facilitate this by providing a platform for depositing datasets linked to publications, supporting secondary analyses that pool evidence across studies to draw robust conclusions, as seen in ecological and biomedical meta-analyses that leverage open data for greater statistical power.^[144]^[145]
