Usage Committee Charter

The mission of the Usage Committee is to ensure an orderly evolution of the metadata terms maintained by the Dublin Core Metadata Initiative. The Usage Committee evaluates proposals for new terms (or changes to existing terms) in light of grammatical principle, semantic clarity, usefulness, and overlap with existing terms. To proposals that are accepted, it assigns a specific status. The Usage Committee also evaluates constructs that use DCMI terms, such as Application Profiles.

Recommendations

The recommendations listed below are semantic or technical specifications that have been approved through DCMI's formal approval process. These specifications are stable and are supported for adoption by the Dublin Core community.

Semantic Recommendations

• DCMI Metadata Terms -- a one-stop source of up-to-date information on DCMI metadata terms.
  Ready-reference subsets of the full set of terms ("DCMI Metadata Terms"):
• Dublin Core Metadata Element Set
• DCMI Type Vocabulary: no longer a separate document - see "DCMI Metadata Terms"
Historical versioning information:
• DCMI Metadata Terms: A complete historical record

Other Recommendations

• DCMI Abstract Model.
• DCMI Box Encoding Scheme: Specification of the spatial limits of a place, and methods for encoding this in a text string.
• DCMI DCSV: A syntax for representing simple structured data in a text string.
• DCMI Period Encoding Scheme: Specification of the limits of a time interval, and methods for encoding this in a text string.
• DCMI Point Encoding Scheme: A point location in space, and methods for encoding this in a text string.
• Expressing Dublin Core metadata using HTML/XHTML meta and link elements. See also: "Notes on DCMI specifications for Dublin Core metadata in HTML/XHTML meta and link elements".
• Expressing Dublin Core metadata using the Resource Description Framework (RDF). See also: "Notes on DCMI specifications for Dublin Core metadata in RDF".
• Guidelines for Encoding Bibliographic Citation Information in Dublin Core Metadata.
• Guidelines for implementing Dublin Core in XML. In 2009, this 2003 DCMI Recommendation may be superseded by current work listed under Proposed Recommendations.
• Namespace Policy for the Dublin Core Metadata Initiative (DCMI).

Proposed Recommendations

Proposed Recommendations are technical specifications that are in the process of being approved through DCMI's formal approval process. These specifications are close to stable and enjoy growing support for adoption by the Dublin Core community.

• Expressing Dublin Core Description Sets using XML (DC-DS-XML). Public Comment was held from 1 to 29 September 2008. A related document, Notes on DC-DS-XML XML Format, describes the development of the format and its relationship to the DCMI Recommendation Guidelines for implementing Dublin Core in XML of April 2003.

Working Drafts

Working Drafts are documents under development. After completion, Working Drafts are submitted to the DCMI Managing Director for approval through DCMI's formal approval process. Publication as a DCMI Working draft does not imply endorsement of any kind by DCMI.

• Description Set Profiles: A constraint language for Dublin Core Application Profiles: http://dublincore.org/documents/2008/03/31/dc-dsp/.
