This Wiki is intended to be used to work on draft copies of documents. Finished documents will be published, in a persistent and citable form, on the [http://dublincore.org/ DCMI Web site] (or elsewhere in some cases). Please announce any significant changes to this Wiki via the DC-ARCHITECTURE@jiscmail.ac.uk list. This Wiki supports the work of the [http://dublincore.org/groups/architecture/ DCMI Architecture Working Group]. == Workplan == * Develop a short document for RDF implementors, clarifying the resource vs. literal string value issue and providing advice on best practice. * Consider possible RDF encoding changes (in light of above issue), carry out an impact analysis and make recommendations. * Finalise the provision of a persistent URI for the latest version of our XML schemes. * Develop an XML binding for Dublin Core metadata which supports all (or a substantial subset) of the features of the [http://dublincore.org/documents/abstract-model/ DCMI Abstract Model]. Revise DCMI XML schemas accordingly. * Finalise revisions to the Namespace Policy for the Dublin Core Metadata Initiative (DCMI) to align use of terminology with other DCMI recommendations. * Evaluate use of GRDDL as mechanism for transforming arbitrary DC/XML documents into RDF (DCMI Abstract Model). * Monitor W3C developments for encoding RDF in XHTML and revise current DC/XHTML guidelines as necessary. * Develop abstract model of 'DC application profiles'. * Consider developing a representation of the DCMI Box, Period and Point encoding schemes using the DCMI Abstract Model. == Documents and resources under construction == The working group (or [wiki:Self:DCRDFTaskforce taskforce]) is currently working on the following documents: === Abstract Model === * [wiki:Self:AMIssues Issues with (and suggested changes to) the DCMI Abstract Model]. * [wiki:Self:AMDraftUpdate DRAFT UPDATE to the DCMI Abstract Model]. === DC in XML === * [http://dublincore.org/documents/2006/05/29/dc-xml/ Expressing Dublin Core metadata using XML] - DC-XML 2006-05-29: the version that went out for public comment.
