OAIS
The term Open Archival Information System (or OAIS) refers to the 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 OAIS itself is not permanent. "Long term" is long ...

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 The TRAC checklist was superseded in 2012 by the ISO 16363, known as the Trusted Digital Repository (TDR) Checklist.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, ...

Digital Preservation
In library science, library and archival science, digital preservation is a formal process to ensure that digital information of continuing value remains accessible and usable in the long term. It involves planning, resource allocation, and application of Preservation (library and archive), preservation methods and Technology, technologies,Day, Michael. "The long-term preservation of Web content". Web archiving (Berlin: Springer, 2006), pp. 177-199. . and combines policies, strategies and actions to ensure access to digital reformatting, 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.Evans, Mark; Carter, Laura. (December 2008). The Challenges of Digital Preservation.

Designated Community
In information and archival communities, a designated community is an identified group of potential consumers who should be able to understand a particular set of information. These consumers may consist of multiple communities, are designated by the archive, and may change over time. Organizations determine their designated communities and establish standards and guidelines that create a mutually beneficial relationship. A designated community can be defined by its occupation, status, or geographic location. The term ''designated community'' is closely aligned with the concept of Open Archival Information System (OAIS). Each one gives the other a central purpose. The OAIS is a repository of information specified for its designated community. The designated community is the reason the OAIS maintains the information it collects. A designated community can change, grow, shrink, or otherwise change over time, depending on the purpose of the information being preserved. Sometimes, a d ...

National Digital Preservation Programme
The National Digital Preservation Program is an initiative run by the Indian Ministry of Electronics and Information Technology (MeitY) to improve digital preservation efforts in India as a means to counter rapidly changing technology and digital obsolescence. The program was initially conceived of in 2008 by the Research & Development in IT (R&D in IT) division of MeitY and was further developed in March 24-25, 2009 during an Indo-US Workshop on International Trends in Digital Preservation that was organized by the Centre for Development of Advanced Computing (C-DAC) of Pune, India, with sponsorship from Indo-US Science & Technology Forum. Following this workshop, C-DAC continued to implement further digital preservation efforts.

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 ...

Sample (material)
In general, a sample is a limited quantity of something which is intended to be similar to and represent a larger amount of that thing(s). The things could be countable objects such as individual items available as units for sale, or an uncountable material. Even though the word "sample" implies a smaller quantity taken from a larger amount, sometimes full biological or mineralogical specimens are called samples if they are taken for analysis, testing, or investigation like other samples. They are also considered samples in the sense that even whole specimens are "samples" of the full population of many individual organisms. The act of obtaining a sample is called "sampling" and can be performed manually by a person or by automatic process. Samples of material can be taken or provided for testing, analysis, investigation, quality control, demonstration, or trial use. Sometimes, sampling may be performed continuously.

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 ...

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 ...
