Architecture Forum deliverables

DCAM: DCMI Abstract Model

• 2007-06-04. "DCMI Abstract Model" is DCMI Recommendation

• No current plans for revision.

DC-RDF

• 2006-05-29. "Expressing Dublin Core metadata using the Resource Description Framework (RDF)" is posted for Public Comment from 30 May to 27 June 2006.

• 2007-06-04. "Expressing Dublin Core metadata using the Resource Description Framework (RDF)" is published as a DCMI Proposed Recommendation, superseding the legacy "Expressing Qualified Dublin Core in RDF/XML" of 2002-05-15.

• 2007-08-14. With publication of revised DCMI Metadata Terms, which formally declares fifteen new elements in the dcterms: namespace, DC-RDF becomes a DCMI Recommendation

• Note: The legacy specification "Expressing Simple Dublin Core in RDF/XML" of 2002-07-31 is superseded by the new DCMI Recommendation.

RDF Schemas

• 2008-01-14. New RDF schemas published for the DCMI namespaces http://purl.org/dc/elements/1.1/, http://purl.org/dc/terms/, http://purl.org/dc/dcmitype/, and http://purl.org/dc/dcam/, with domains and ranges for properties and with terminology aligned with DCMI Abstract Model. These changes were also reflected in the revised specification DCMI Metadata Terms (see also Domains and Ranges for DCMI Properties).

• Note: DCMI term declarations represented in RDF schema language are discussed in an explanatory note.

DC-HTML

• 2007-11-05. Legacy "Expressing Dublin Core in HTML/XHTML meta and link elements" of 2003-11-30 is replaced by a revised DCMI Proposed Recommendation for Public Comment.

• 2007-12-03. Public Comment closes on "Expressing Dublin Core metadata using HTML/XHTML meta and link elements" ([ http://dublincore.org/documents/2007/11/05/dc-html/ DC-HTML)].

• 2007-12-15. Advancement to "DCMI Recommendation" is contingent on completion of "Notes on expressing Dublin Core metadata in HTML and XHTML" as a note on "backwards compatibility".

DC-XML

• 2003-04-02. "Guidelines for implementing Dublin Core in XML" is published as a DCMI Recommendation.

• 2007-06-27. "Expressing Dublin Core metadata in XML" was posted for public comment from 30 May to 27 June 2006. The specification was accompanied by a set of example XML schemas; an additional document "DC-XML and XML Schema" about "customizing the schemas for various application profiles"; and an XSLT stylesheet for using GRDDL to extract RDF/XML from DC-XML (see also the [http://dublincore.org/architecturewiki/DCXMLRevision/Comments summary of comments).

• 2006-09-18. Draft guidelines are posted on the wiki, differentiating between "DC-XML Full" (with its instance documents) and [http://dublincore.org/architecturewiki/DCXMLRevision/DCXMLMGuidelines/2006-09-18 "DC-XML Minimum" (with its [http://dublincore.org/architecturewiki/DCXMLRevision/DCXMLFInstances/2006-09-18 instance documents).

• 2007-12-05: As of December 2007, the Architecture Forum is moving forward with "full" format and discussing requirements for a "minimal" format on the mailing list.

• Note: XML schemas to support the Guidelines for implementing DC in XML recommendation are discussed in an explanatory note.
