In library and archival science, digital preservation is a formal endeavor to ensure that digital information of continuing value remains accessible and usable. It involves planning, resource allocation, and application of preservation methods and technologies, and it combines policies, strategies and actions to ensure access to reformatted and "born-digital" content, regardless of the challenges of media failure and technological change. The goal of digital preservation is the accurate rendering of authenticated content over time. The Association for Library Collections and Technical Services Preservation and Reformatting Section of the American Library Association, defined digital preservation as combination of "policies, strategies and actions that ensure access to digital content over time." According to the Harrod's Librarian Glossary, digital preservation is the method of keeping digital material alive so that they remain usable as technological advances render original hardware and software specification obsolete.
DSpace is an open source repository software package typically used for creating open access repositories for scholarly and/or published digital content. While DSpace shares some feature overlap with content management systems and document management systems, the DSpace repository software serves a specific need as a digital archives system, focused on the long-term storage, access and preservation of digital content. The optional DSpace registry lists almost three thousand repositories all over the world.
Fedora is a digital asset management (DAM) content repository architecture upon which institutional repositories, digital archives, and digital library systems might be built. Fedora is the underlying architecture for a digital repository, and is not a complete management, indexing, discovery, and delivery application. It is a modular architecture built on the principle that interoperability and extensibility are best achieved by the integration of data, interfaces, and mechanisms as clearly defined modules.
GNOME Commander is a 'two panel' graphical file manager for GNOME. It is built using the GTK+ toolkit and GVfs.
Building Resources for Integrated Cultural Knowledge Services (BRICKS) is an open-source software framework for the management of distributed digital assets. BRICKS was deployed on cultural institutions under the umbrella of the BRICKS Cultural Heritage Network, a community of cultural heritage, scientific and industrial organizations across Europe. The software itself is shared under the GNU Lesser General Public License (LGPL).
BASE is a multi-disciplinary search engine to scholarly internet resources, created by Bielefeld University Library in Bielefeld, Germany. It is based on free and open-source software such as Apache Solr and VuFind. It harvests OAI metadata from institutional repositories and other academic digital libraries that implement the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH), and then normalizes and indexes the data for searching. In addition to OAI metadata, the library indexes selected web sites and local data collections, all of which can be searched via a single search interface.
Documentum is an enterprise content management platform, now owned by OpenText, as well as the name of the software company that originally developed the technology. EMC acquired Documentum for US$1.7 billion in December, 2003. The Documentum platform was part of EMC's Enterprise Content Division (ECD) business unit, one of EMC's four operating divisions.
PREservation Metadata: Implementation Strategies (PREMIS) is the de facto digital preservation metadata standard.
A digital library, also called an online library, an internet library, a digital repository, a library without walls, or a digital collection is an online database of digital objects that can include text, still images, audio, video, digital documents, or other digital media formats or a library accessible through the internet. Objects can consist of digitized content like print or photographs, as well as originally produced digital content like word processor files or social media posts. In addition to storing content, digital libraries provide means for organizing, searching, and retrieving the content contained in the collection. Digital libraries can vary immensely in size and scope, and can be maintained by individuals or organizations. The digital content may be stored locally, or accessed remotely via computer networks. These information retrieval systems are able to exchange information with each other through interoperability and sustainability.
The Handle System is the Corporation for National Research Initiatives's proprietary registry assigning persistent identifiers, or handles, to information resources, and for resolving "those handles into the information necessary to locate, access, and otherwise make use of the resources".
OpenBiblio is an open source Integrated Library System. The software is popular with small and rural libraries worldwide due to its simplicity, extensive language support, and good documentation.
Pimcore is an open-source enterprise PHP software platform for product information management (PIM), master data management (MDM), customer data management (CDP), digital asset management (DAM), content management (CMS), and digital commerce.
Dryad is an international open-access repository of research data, especially data underlying scientific and medical publications. Dryad is a curated general-purpose repository that makes data discoverable, freely reusable, and citable. The scientific, educational, and charitable mission of Dryad is to provide the infrastructure for and promote the re-use of scholarly research data.
An open repository or open-access repository is a digital platform that holds research output and provides free, immediate and permanent access to research results for anyone to use, download and distribute. To facilitate open access such repositories must be interoperable according to the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH). Search engines harvest the content of open access repositories, constructing a database of worldwide, free of charge available research.
Islandora is a free and open-source software digital repository system based on Drupal and integrating with additional applications, including Fedora Commons. It is open source software. Islandora was originally developed at the University of Prince Edward Island by the Robertson Library and is now maintained by the Islandora Foundation, which has a mission to, "promote collaboration through transparency and consensus building among Islandora community members, and to steward their shared vision for digital curation features through a body of software and knowledge."
ResCarta Toolkit is an open source software package used to create open access repositories for local history and published digital content. ResCarta Toolkit focuses on the use of open standard file formats and metadata standards to create archives that are sustainable over time. It includes software for creation of digital objects, indexing of metadata and content, display tools and checksum validation.
The International Image Interoperability Framework defines several application programming interfaces that provide a standardised method of describing and delivering images over the web, as well as "presentation based metadata" about structured sequences of images. If institutions holding artworks, books, newspapers, manuscripts, maps, scrolls, single sheet collections, and archival materials provide IIIF endpoints for their content, any IIIF-compliant viewer or application can consume and display both the images and their structural and presentation metadata.
Samvera, originally known as Hydra, is an open-source digital repository software product. Samvera main components are Fedora Commons, Solr, Blacklight, and HydraHead. Each Samvera implementation is called a "head".
Keeping the foresight of rapidly changing technologies and rampant digital obsolescence, in 2008, the R & D in IT Group, Ministry of Electronics and Information Technology, Government of India envisaged to evolve Indian digital preservation initiative. In order to learn from the experience of developed nations, during March 24–25, 2009, an Indo-US Workshop on International Trends in Digital Preservation was organized by C-DAC, Pune with sponsorship from Indo-US Science & Technology Forum, which lead to more constructive developments towards formulation of the national program.
