, The Program Committee for DC-2007, to be held in Singapore from 27 through 31 August 2007, has issued the Call for Papers for the conference. Please note that the deadline for submission of papers is 2 April 2007.

, The 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 befrom 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 http://purl.org/dc/elements/1.1/ — in the namespace http://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.

, The next meetings of the DCMI Board of Trustees and Usage Board will take place in Barcelona in March 2007 at the premises of Barcelona Media. The Usage Board meeting is scheduled for 16 and 17 March, while the Trustees will meet on 18 March 2007.

, The DCMI Usage Board has completed an editorial revision of terms in the Dublin Core Metadata Element Set, bringing definitions and usage comments into line with the DCMI Abstract Model. Documentation is available in revised Web pages, RDF schemas, and in a response to comments received during the Public Comment period.
