DCMI Abstract Model & DCMI vocabulary of domain and range classes
( 12/02/2007 ) |
Public CommentsThe DCMI Abstract Model, which attained the status of DCMI Recommendation in March 2005, has been revised in light of discussion and feedback from the DCMI Architecture Working Group, the DCMI Usage Board, and the broader community. This revised version of the Abstract Model has been posted for a four-week public comment period. A revised DCMI Namespace Policy proposing a new DCMI namespace for Abstract Model entities has been posted for comment at the same time. For more information please consult a longer announcement on the DC-ARCHITECTURE mailing list. Interested members of the public are invited to post comments on these Proposed Recommendations to the DC-ARCHITECTURE mailing list, including "[DCAM Public Comment]" in the subject line. Public Comment will be open from 5 February through 5 March 2007.
In connection with the revision of the DCMI Abstract Model, Andy Powell has developed a proposal for a vocabulary of classes and their use as the domains and ranges of metadata elements maintained by DCMI. Domains and ranges specify -- in a form usable for inferencing -- what kind of described resources and value resources are associated with a given property. The assignment of formal domains and ranges makes the meanings implicit in natural-language definitions available for machine processing. So as not to affect the conformance of legacy implementations of Simple Dublin Core in RDF (see notes on this issue), DCMI proposes to replicate the fifteen elements of the Dublin Core Metadata Element Set — currently identified using the namespace purl.org/dc/elements/1.1/ — in the namespace purl.org/dc/terms/. Terms in the former namespace are to remain unspecified as to domain and range; terms in the latter are to be assigned domains and ranges as outlined in the proposal. "Domains and Ranges for DCMI Properties" has been posted for Public Comment from 5 February through 5 March 2007. Interested members of the public are invited to post comments to the DC-ARCHITECTURE mailing list, including "[Domains and Ranges Public Comment]" in the subject line. After Public Comment, the proposal will be submitted to the DCMI Usage Board for a further review and decision.More information |
