innovation in metadata design, implementation & best practice

Dublin Core

The original Dublin Core of thirteen (later fifteen) elements was first published in the report of a workshop in 1995. In 1998, this was formalized in the Internet Engineering Task Force standard RFC 5791, and discussions began about making it a standard of the (US) National Information Standards Organization (NISO). This led to the publication of ANSI/NISO Z39.85-2001 and the International Standards Organization Standard 15836-2003. The most recent updates of these standards are RFC 5791 (2010), Z39-85-2012, and ISO 15836-1:2017. Publication of a Part 2 to the ISO standard, covering several dozen properties and classes that have been added to DCMI namespaces since 1999, is expected in 2019.

Starting in 2002, DCMI grew into the role of "de facto" standards agency by maintaining its own, updated documentation for DCMI Metadata Terms. The DCMI Usage Board currently serves as the maintenance agency for ISO 15836.

In addition to these semantic specifications, DCMI working groups have developed specifications on other topics of relevance to metadata, such as encoding syntaxes, usage guidelines, and metadata models. In the rapidly evolving environment of the World Wide Web, most of these specifications have been superseded over time, sometimes after influencing subsequent work by other technical communities, notably the World Wide Web Consortium.
