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. == Progress == The first two work items above are being undertaken by the Self:DCRDFTaskforce. See the taskforce's wiki for an up to date snapshot of the status of the associated documents. Pete Johnston has been working on the two work items associated with the XML encoding guidelines. A summary of the current situation w.r.t. URIs for DCMI's XML schemas is available [http://www.jiscmail.ac.uk/cgi-bin/webadmin?A2=ind0501&L=dc-architecture&T=0&F=&S=&P=839 here] with agreement being to move forward on the basis of proposal 1(b). A revised DRAFT DCMI Self:NamespacePolicy has been drafted. Work on the final four work items (GRDDL, RDF in XHTML, DC application profile model, and Box/Period/Point) has not yet started. == Documents and resources under construction == The working group (or taskforce) is currently working on the following documents: * [wiki:Self:NamespacePolicy DRAFT UPDATE to the Namespace Policy for the Dublin Core Metadata Initiative (DCMI)] * [wiki:Self:RDFValueStringsClarification Clarification of the recommendations for encoding 'value strings' in DC RDF/XML] * [wiki:Self:DCRDFGuidelines Guidelines for encoding DC metadata using the RDF Model] * [wiki:Self:DCPropertyDomainsRanges DC Property Domains and Ranges] * [wiki:Self:ProposedPropertyDefinitions Proposed changes to DCMI property definitions] * [wiki:Self:TermDecisionTree DCMI Term Decision Tree] The group is also maintaining a list of issues and possible changes to the DCMI Abstract Model: * [wiki:Self:AMIssues Issues with (and suggested changes to) the DCMI Abstract Model] == Published/stable documents and resources == * [http://dublincore.org/documents/abstract-model/ DCMI Abstract Model] * [http://dublincore.org/documents/2002/07/31/dcmes-xml/ Expressing Simple Dublin Core in RDF/XML] * [http://dublincore.org/documents/dc-xml-guidelines/ Guidelines for implementing Dublin Core in XML] * [http://dublincore.org/documents/dcq-rdf-xml/ Expressing Qualified Dublin Core in RDF / XML] * [http://dublincore.org/documents/dcq-html/ Expressing Dublin Core in HTML/XHTML meta and link elements] * [http://dublincore.org/documents/dcmi-namespace/ Namespace Policy for the Dublin Core Metadata Initiative (DCMI)] * [http://dublincore.org/documents/dcmi-terms/ DCMI Metadata Terms] * [http://dublincore.org/documents/dces/ Dublin Core Metadata Element Set, Version 1.1: Reference Description] * [http://dublincore.org/schemas/rdfs/ DCMI term declarations represented in RDF schema language] * [http://dublincore.org/schemas/xmls/ XML schemas to support the Guidelines for implementing DC in XML recommendation] * [http://dublincore.org/groups/architecture/ DCMI Architecture Working Group home page] * [http://www.jiscmail.ac.uk/lists/dc-architecture.html DC-ARCHITECTURE mailing list archives] == Taskforces == * The [wiki:Self:DCRDFTaskforce DC RDF Taskforce] is addressing the first two bullet points above. == Meetings == === DC-2005, Madrid === DC Architecture session presentations: * Andy Powell - Introduction, namespace policy, XML guidelines, workplan for next year: [http://dublincore.org/architecturewiki/DCRDFTaskforce?action=AttachFile&do=get&target=dc-arch-meeting.ppt Powerpoint] * Pete Johnston - XML and the DCMI Abstract Model: [http://www.ukoln.ac.uk/metadata/dcmi/dc-xml-issues/ Paper (HTML)] [http://www.ukoln.ac.uk/metadata/dcmi/dc2005/dc-xml/dc-xml.ppt Presentation (Powerpoint)] [http://www.ukoln.ac.uk/metadata/dcmi/dc2005/dc-xml/ Presentation (HTML)] === DC-2004, Shanghai === DC Architecture session presentations: * Andy Powell - Introduction, Abstract Model, RDF Issues, report: [http://www.ukoln.ac.uk/metadata/dcmi/dc2004/archwg/archwg.ppt Powerpoint] [http://www.ukoln.ac.uk/metadata/dcmi/dc2004/archwg/archwg.htm HTML] * Pete Johnston - XML Schema: [http://www.ukoln.ac.uk/metadata/dcmi/dc2004/xmlschema/xmlschema.ppt Powerpoint] [http://www.ukoln.ac.uk/metadata/dcmi/dc2004/xmlschema/ HTML] * Tom Baker - Identifiers for Historical Versions of Metadata Terms: [http://www.bi.fhg.de/People/Thomas.Baker/Architecture.ppt Powerpoint] [http://www.jiscmail.ac.uk/cgi-bin/webadmin?A2=ind0410&L=dc-architecture&T=0&F=&S=&P=4565 Meeting report]. == Example descriptions == * [wiki:Self:AdaptabilityApplicationProfile Example description based on the proposed Adaptability Application Profile] == Other related work == * [wiki:Self:LinkingDCDescriptionsToODRLExpressions Linking DC Descriptions to ODRL Expressions] ---- '''New to this wiki?'''
