Open Archival Information System
The term Open Archival Information System (or OAIS) refers to the International Organization for Standardization , ISO OAIS Reference Model ''for'' an OAIS. This reference model is defined by recommendatioCCSDS 650.0-M-2-Sof the Consultative Committee for Space Data Systems; this text is identical tISO 14721:2025 The CCSDS's purview is space agencies, but the OAIS model it developed has proved useful to other organizations and institutions with digital archiving needs. OAIS, known a is widely accepted and utilized by various organizations and disciplines, both national and international, and was designed to ensure preservation. The OAIS standard, published in 2005, is considered the optimum standard to create and maintain a digital repository over a long period of time. The OAIS model can be applied to various archives, e.g., open access, closed, restricted, "dark", or proprietary. The information being maintained has been deemed to need "long term preservation", even if the O ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Open Archives Initiative
The Open Archives Initiative (OAI) was an informal organization, in the circle around the colleagues Herbert Van de Sompel, Carl Lagoze, Michael L. Nelson and Simeon Warner, to develop and apply technical interoperability standards for archives to share catalogue information (metadata).Open Archives Initiative -> About OAI/ref> The group got together in the late late 1990s and was active for around twenty years. OAI coordinated in particular three specification activities: OAI-PMH, OAI-ORE and ResourceSync. All along the group worked towards building a "low-barrier interoperability framework" for archives (institutional repository, institutional repositories) containing digital content (digital library, digital libraries) to allow people (service providers) harvest metadata (from data providers). Such sets of metadata are since then harvested to provide "value-added services", often by combining different data sets. OAI has been involved in developing a technological framework an ...

Bibliothèque Nationale De France
The (; BnF) is the national library of France, located in Paris on two main sites, ''Richelieu'' and ''François-Mitterrand''. It is the national repository of all that is published in France. Some of its extensive collections, including books and manuscripts but also precious objects and artworks, are on display at the BnF Museum (formerly known as the ) on the Richelieu site. The National Library of France is a public establishment under the supervision of the Ministry of Culture. Its mission is to constitute collections, especially the copies of works published in France that must, by law, be deposited there, conserve them, and make them available to the public. It produces a reference catalogue, cooperates with other national and international establishments, as well as participates in research programs.

Data Curation
Data ( , ) are a collection of discrete or continuous values that convey information, describing the quantity, quality, fact, statistics, other basic units of meaning, or simply sequences of symbols that may be further interpreted formally. A datum is an individual value in a collection of data. Data are usually organized into structures such as tables that provide additional context and meaning, and may themselves be used as data in larger structures. Data may be used as variables in a computational process. Data may represent abstract ideas or concrete measurements. Data are commonly used in scientific research, economics, and virtually every other form of human organizational activity. Examples of data sets include price indices (such as the consumer price index), unemployment rates, literacy rates, and census data. In this context, data represent the raw facts and figures from which useful information can be extracted. Data are collected using techniques suc ...

OpenID Connect
OpenID is an open standard and decentralized authentication protocol promoted by the non-profit OpenID Foundation. It allows users to be authenticated by co-operating sites (known as relying parties, or RP) using a third-party identity provider (IDP) service, eliminating the need for webmasters to provide their own ''ad hoc'' login systems, and allowing users to log in to multiple unrelated websites without having to have a separate identity and password for each. Users create accounts by selecting an OpenID identity provider, and then use those accounts to sign on to any website that accepts OpenID authentication. Several large organizations either issue or accept OpenIDs on their websites. The OpenID standard provides a framework for the communication that must take place between the identity provider and the OpenID acceptor (the "relying party"). An extension to the standard (the OpenID Attribute Exchange) facilitates the transfer of user attributes, such as name and gende ...

Representational State Transfer
REST (Representational State Transfer) is a software architectural style that was created to describe the design and guide the development of the architecture for the World Wide Web. REST defines a set of constraints for how the architecture of a distributed, Internet-scale hypermedia system, such as the Web, should behave. The REST architectural style emphasises uniform interfaces, independent deployment of components, the scalability of interactions between them, and creating a layered architecture to promote caching to reduce user-perceived latency, enforce security, and encapsulate legacy systems. REST has been employed throughout the software industry to create stateless, reliable, web-based applications. An application that adheres to the REST architectural constraints may be informally described as ''RESTful'', although this term is more commonly associated with the design of HTTP-based APIs and what are widely considered best practices regarding the "verbs" ( HTTP ...

Business Process Model And Notation
Business Process Model and Notation (BPMN) is a graphical representation for specifying business processes in a business process model. Originally developed by the Business Process Management Initiative (BPMI), BPMN has been maintained by the Object Management Group (OMG) since the two organizations merged in 2005. Version 2.0 of BPMN was released in January 2011, at which point the name was amended to Business Process Model ''and'' Notation to reflect the introduction of execution semantics, which were introduced alongside the existing notational and diagramming elements. Though it is an OMG specification, BPMN is also ratified as ISO 19510. The latest version is BPMN 2.0.2, published in January 2014. Overview Business Process Model and Notation (BPMN) is a standard for business process modeling that provides a graphical notation for specifying business processes in a ''Business Process Diagram'' (BPD), based on a flowcharting technique very similar to activity diagrams from U ...

Open Packaging Conventions
The Open Packaging Conventions (OPC) is a container-file technology initially created by Microsoft to store a combination of XML and non-XML files that together form a single entity such as an Open XML Paper Specification (OpenXPS) document. OPC-based file formats combine the advantages of leaving the independent file entities embedded in the document intact and resulting in much smaller files compared to normal use of XML. Specifications The OPC is specified in Part 2 of the Office Open XML standards ISO/IEC 29500:2008 and ECMA-376.ISO/IEC 29500-2:2008 - Information technology -- Document description and processing languages -- Office Open XML File Formats ...

Trustworthy Repositories Audit & Certification
Trustworthy Repositories Audit & Certification (TRAC) is a document describing the metrics of an OAIS-compliant digital repository that developed from work done by the OCLC/ RLG Programs and National Archives and Records Administration (NARA) task force initiative. The TRAC checklist is an Auditing tool to assess the reliability, commitment and readiness of institutions to assume long-term preservation responsibilities. Currently the repository is under the care of the CRL who are utilizing it in several independent projects. The TRAC checklist was superseded in 2012 by the ISO 16363, known as the Trusted Digital Repository (TDR) Checklist. History In 1996 the Consultative Committee for Space Data Systems established a task force that developed OAIS, a high-level model for the operation of archives. OAIS was accepted as ISO 14721 in 2002. The original task force stated that an independent auditing method was necessary to certify OAIS-compliance and thus engender trust. However, ...

Centre For Development Of Advanced Computing
The Centre for Development of Advanced Computing (C-DAC) is an Indian autonomous scientific society, operating under the Ministry of Electronics and Information Technology. History C-DAC was created in November 1987, initially as the Centre for Development of Advanced Computing Technology (C-DACT). In 1988, the US Government refused to sell India a Cray supercomputer due to concerns about India using it to develop nuclear weapons. In response India started development of its own supercomputer, and C-DACT was created as part of this programme. Dr Vijay Bhatkar was hired as the director of C-DACT. The project was given an initial run of three years and an initial funding of 30,00,00,000, the cost of a Cray supercomputer. A prototype computer was benchmarked at the 1990 Zurich Super-computing Show. It demonstrated that India had the second most powerful, publicly demonstrated, supercomputer in the world after the United States. The final result of the effort was the PARAM ...

JSTOR
JSTOR ( ; short for ''Journal Storage'') is a digital library of academic journals, books, and primary sources founded in 1994. Originally containing digitized back issues of academic journals, it now encompasses books and other primary sources as well as current issues of journals in the humanities and social sciences. It provides full-text searches of almost 2,000 journals. Most access is by subscription but some of the site is public domain, and open access content is available free of charge. History William G. Bowen, president of Princeton University from 1972 to 1988, founded JSTOR in 1994. JSTOR was originally conceived as a solution to one of the problems faced by libraries, especially research and university libraries, due to the increasing number of academic journals in existence. Most libraries found it prohibitively expensive in terms of cost and space to maintain a comprehensive collection of journals. By digitizing many journal titles, JSTOR allowed libraries ...
