The Dublin Core, also known as the Dublin Core Metadata Element Set (DCMES), is a set of fifteen main metadata items for describing digital or physical resources. It was the first metadata standard for describing web content. The Dublin Core Metadata Initiative (DCMI) is responsible for formulating the Dublin Core; DCMI is a project of the Association for Information Science and Technology (ASIS&T), a non-profit organization.
The Resource Description Framework (RDF) is a World Wide Web Consortium (W3C) standard originally designed as a data model for metadata. It has come to be used as a general method for description and exchange of graph data. RDF provides a variety of syntax notations and data serialization formats, with Turtle currently being the most widely used notation.
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). 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 containing digital content to allow people harvest metadata. Such sets of metadata are since then harvested to provide "value-added services", often by combining different data sets.
WebDAV is a set of extensions to the Hypertext Transfer Protocol (HTTP), which allows user agents to collaboratively author contents directly in an HTTP web server by providing facilities for concurrency control and namespace operations, thus allowing Web to be viewed as a writeable, collaborative medium and not just a read-only medium. WebDAV is defined in RFC 4918 by a working group of the Internet Engineering Task Force (IETF).
The Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) is a protocol developed for harvesting metadata descriptions of records in an archive so that services can be built using metadata from many archives. An implementation of OAI-PMH must support representing metadata in Dublin Core, but may also support additional representations.
Learning Object Metadata is a data model, usually encoded in XML, used to describe a learning object and similar digital resources used to support learning. The purpose of learning object metadata is to support the reusability of learning objects, to aid discoverability, and to facilitate their interoperability, usually in the context of online learning management systems (LMS).
OAIster is an online combined bibliographic catalogue of open access material aggregated using OAI-PMH.
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.
The AgMES initiative was developed by the Food and Agriculture Organization (FAO) of the United Nations and aims to encompass issues of semantic standards in the domain of agriculture with respect to description, resource discovery, interoperability, and data exchange for different types of information resources.
Agricultural Information Management Standards (AIMS) is a web site managed by the Food and Agriculture Organization of the United Nations (FAO) for accessing and discussing agricultural information management standards, tools and methodologies connecting information workers worldwide to build a global community of practice. Information management standards, tools and good practices can be found on AIMS:
PREservation Metadata: Implementation Strategies (PREMIS) is the de facto digital preservation metadata standard.
A resource map (ReM) is a concept of the ORE Model for associating an identity with compound digital objects and making assertions about their structure and semantics. Compound objects combine distributed resources, including multiple media types.
Herbert Van de Sompel is a Belgian librarian, computer scientist, and musician, most known for his role in the development of the Open Archives Initiative (OAI) and standards such as OpenURL, Object Reuse and Exchange, and the OAI Protocol for Metadata Harvesting.
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".
AGRIS is a global public domain database with more than 12 million structured bibliographical records on agricultural science and technology. It became operational in 1975 and the database was maintained by Coherence in Information for Agricultural Research for Development, and its content is provided by more than 150 participating institutions from 65 countries. The AGRIS Search system, allows scientists, researchers and students to perform sophisticated searches using keywords from the AGROVOC thesaurus, specific journal titles or names of countries, institutions, and authors.
ISO/IEC 19788Information technology – Learning, education and training – Metadata for learning resources is a multi-part standard prepared by subcommittee SC 36 of the joint technical committee ISO/IEC JTC 1, Information Technology for Learning, Education and Training.
As a general definition, paradata are usage data about learning resources that include not just quantitative metrics, but also pedagogic context, as inferred through the actions of educators and learners. Paradata may be operationalized as a specific type of metadata, however the construct differs from traditional descriptive metadata that classify the properties of the learning resource itself, and instead involves the capture—and open resharing—of in situ information about online users’ actions related to the resource. Learning resource paradata is generated through user processes of searching for content, identifying interest for subsequent use, correlating resources to specific learning goals or standards, and integrating content into educational practices. Paradata may include individual or aggregate user interactions such as viewing, downloading, sharing to other users, favoriting, and embedding reusable content into derivative works, as well as contextualizing activities such as aligning content to educational standards, adding tags, and incorporating resources into curriculum. Context about users is also of interest as paradata, including grade level or subject taught, experience level, or geographic location—as is information about the curricular relevance, audience, methodologies, and instructional settings of use as a resource is adopted by practitioners. Paradata are generally anonymized and/or aggregated at the community level to protect the privacy of individual users as data are shared between learning communities. Paradata may be expressed in realtime data streaming as user actions occur, or as periodic reporting of user activities over a range of time.
The Asset Description Metadata Schema (ADMS) is a common metadata vocabulary to describe standards, so-called interoperability assets, on the Web.
In computing, a Research Object is a method for the identification, aggregation and exchange of scholarly information on the Web. The primary goal of the research object approach is to provide a mechanism to associate related resources about a scientific investigation so that they can be shared using a single identifier. As such, research objects are an advanced form of Enhanced publication.
