![]() ![]() Language – "A language of the resource".Identifier – "An unambiguous reference to the resource within a given context".Format – "The file format, physical medium, or dimensions of the resource".Description – "An account of the resource".Date – "A point or period of time associated with an event in the lifecycle of the resource".Creator – "An entity primarily responsible for making the resource".Coverage – "The spatial or temporal topic of the resource, the spatial applicability of the resource, or the jurisdiction under which the resource is relevant".Contributor – "An entity responsible for making contributions to the resource".The original DCMES Version 1.1 consists of 15 metadata elements, defined this way in the original specification: Because the definition of the terms often contains domains and ranges, which may not be compatible with the pre-RDF definitions used for the original 15 Dublin Core elements, there is a separate namespace for the original 15 elements as previously defined. The full set of elements is found under the namespace. Since 2012, the two have been incorporated into the DCMI Metadata Terms as a single set of terms using the RDF data model. Simple Dublin Core comprised 15 elements Qualified Dublin Core included three additional elements (Audience, Provenance and RightsHolder), as well as a group of element refinements (also called qualifiers) that could refine the semantics of the elements in ways that may be useful in resource discovery. The Dublin Core standard originally included two levels: Simple and Qualified. This policy describes how terms are assigned and also sets limits on the amount of editorial changes allowed to the labels, definitions, and usage comments. Ĭurrently, any and all changes that are made to the Dublin Core standard, are reviewed by a DCMI Usage Board within the context of a DCMI Namespace Policy (DCMI-NAMESPACE). In 2008, DCMI separated from OCLC and incorporated as an independent entity. DCMI's activities include consensus-driven working groups, global conferences and workshops, standards liaison, and educational efforts to promote widespread acceptance of metadata standards and practices. The Dublin Core Metadata Initiative (DCMI) provides an open forum for the development of interoperable online metadata standards for a broad range of purposes and of business models. As part of an extended set of DCMI metadata terms, Dublin Core became one of the most popular vocabularies for use with RDF, more recently in the context of the linked data movement. ![]() During that time, the World Wide Web Consortium's work on a generic data model for metadata, the Resource Description Framework (RDF), was maturing. Starting in 2000, the Dublin Core community focused on " application profiles" – the idea that metadata records would use Dublin Core together with other specialized vocabularies to meet particular implementation requirements. In 1999, the first Dublin Core encoding standard was in HTML. The semantics of Dublin Core were established and are maintained by an international, cross-disciplinary group of professionals from librarianship, computer science, text encoding, museums, and other related fields of scholarship and practice. "Core" refers to the metadata terms as "broad and generic being usable for describing a wide range of resources". "Dublin" refers to Dublin, Ohio, USA where the schema originated during the 1995 invitational OCLC/NCSA Metadata Workshop, hosted by the OCLC (known at that time as Online Computer Library Center), a library consortium based in Dublin, and the National Center for Supercomputing Applications (NCSA). ![]() The resources described using the Dublin Core may be digital resources (video, images, web pages, etc.) as well as physical resources such as books or works of art.ĭublin Core metadata may be used for multiple purposes, from simple resource description to combining metadata vocabularies of different metadata standards, to providing interoperability for metadata vocabularies in the linked data cloud and Semantic Web implementations. "Dublin Core" is also used as an adjective for Dublin Core metadata, a style of metadata that draws on multiple Resource Description Framework (RDF) vocabularies, packaged and constrained in Dublin Core application profiles. The core properties are part of a larger set of DCMI Metadata Terms. The Dublin Core Metadata Initiative (DCMI), which formulates the DublinĬore, is a project of the Association for Information Science and Technology (ASIS&T), a non-profit organization. This fifteen-element Dublin Core has been formally standardized as ISO 15836, ANSI/NISO Z39.85, and IETF RFC 5013. The Dublin Core, also known as the Dublin Core Metadata Element Set (DCMES), is a set of fifteen "core" elements (properties) for describing resources.
