Network Working Group J. Kunze Request for Comments: 5013 University of California Obsoletes: 2413 T. Baker Category: Informational Dublin Core Metadata Initiative August 2007 The Dublin Core Metadata Element Set Status of This Memo This memo provides information for the Internet community. It does not specify an Internet standard of any kind. Distribution of this memo is unlimited. Abstract This document defines fifteen metadata elements for resource description in a cross-disciplinary information environment. 1. Introduction The Dublin Core Metadata Workshop Series began in 1995 with an invitational workshop that brought together librarians, digital library researchers, content experts, and text-markup experts to promote better discovery standards for electronic resources. The resulting metadata element set defines fifteen metadata elements for resource description in a cross-disciplinary information environment. This document contains the current text of Dublin Core "Version 1.1". Version 1.1 is the basis of ANSI/NISO Z39.85-2001 [Z39.85]. The text in the present RFC closely follows the text in the 2007 revision of ANSI/NISO Z39.85, especially Sections 2-6 and 10-12 [Z39.85-2007]. The present RFC obsoletes RFC 2413 [RFC2413], which was the first published version of the Dublin Core ("Version 1.0"). The main differences between the present RFC and RFC 2413 are in the wording of definitions -- for Contributor and Date (semantically broadened), for Relation (clarified), and in the general removing of redundant references to "the content of" a resource. In addition, the present RFC recommends lowercase element names (consistent with RDF property types), remains silent about the unrestrictedness of element ordering and repeatability (application profiles being the proper place to discuss such topics), and references the current abstract model, vocabularies, and namespace policies in which the Dublin Core is embedded. Kunze & Baker Informational [Page 1] RFC 5013 Dublin Core Metadata August 2007 2. Foreword The Dublin Core Metadata Element Set is a vocabulary of fifteen properties for use in resource description. The name "Dublin" is due to its origin at a 1995 invitational workshop in Dublin, Ohio; "core" because its elements are broad and generic, usable for describing a wide range of resources. The fifteen element "Dublin Core" described in this document is part of a larger set of metadata vocabularies and technical specifications maintained by the Dublin Core Metadata Initiative (DCMI). The full set of vocabularies, DCMI Metadata Terms [DCTERMS], also includes a set of resource classes, the DCMI Type Vocabulary [DCTYPE]. The terms in DCMI vocabularies are intended to be used in combination with terms from other compatible vocabularies in the context of application profiles and on the basis of the DCMI Abstract Model [DCAM]. All changes made to terms of the Dublin Core Metadata Element Set since 2001 have been reviewed by a DCMI Usage Board in the context of a DCMI Namespace Policy [DCNMSPC]. The namespace policy describes how DCMI terms are assigned Uniform Resource Identifiers (URIs) and sets limits on the range of editorial changes that may allowably be made to the labels, definitions, and usage comments associated with existing DCMI terms. 3. Scope and Purpose The Dublin Core Metadata Element Set is a standard for cross-domain resource description. As in RFC 3986 [RFC3986], "Uniform Resource Identifier (URI): Generic Syntax", this specification does not limit the scope of what might be a resource. The elements described in this document are typically used in the context of an application profile which constrains or specifies their use in accordance with local or community-based requirements and policies. The specification of such implementation detail is outside the scope of this document. Kunze & Baker Informational [Page 2] RFC 5013 Dublin Core Metadata August 2007 4. Definitions DCMI -- the Dublin Core Metadata Initiative, maintenance agency for Dublin Core Metadata Element Set. Resource -- anything that might be identified (the same definition as in RFC 3986 and in the DCMI Abstract Model). Lifecycle of a resource -- a sequence of events that mark the development and use of a resource. Some examples of events in a lifecycle are: conception of an invention, creation of a draft, revision of an article, publication of a book, acquisition by aShow full document text
