DCMI Architecture Working Group Wiki

Chair:	AndyPowell, Eduserv Foundation
Status:	This working group is currently active.
Established:	2000-10-06
Charter:	The objectives of the working group are to discuss and develop a model, strategy and roadmap for the practical deployment of Dublin Core metadata using mainstream Web technologies (XML/RDF/XHTML).

IMPORTANT: Do not cite materials in this Wiki other than for the purposes of collaborating on document creation. 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 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 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 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 taskforce) is currently working on the following documents:

• Issues with (and suggested changes to) the DCMI Abstract Model.

• DRAFT UPDATE to the DCMI Abstract Model.

• Expressing Dublin Core metadata using XML - the version that went out for public comment.

• Expressing Dublin Core metadata using XML - an alternative version using the dcx:statement construct. (Some example DC-XML instances corresponding to this version are also available).

• Expressing Dublin Core metadata using the Resource Description Framework (RDF) - the version that went out for public comment

• summary of the comments received on both DC-XML and DC-RDF

• DRAFT UPDATE to the Namespace Policy for the Dublin Core Metadata Initiative (DCMI)

• Clarification of the recommendations for encoding 'value strings' in DC RDF/XML

The following documents being developed and maintained by the DCMI Usage Board] are also useful:

• DC Property Domains and Ranges

• DCMI Term Decision Tree

A summary of the comments received on both DC-XML and DC-RDF is available.

and a resulting Draft update to the DCMI Abstract Model

Other DRAFT recommended resources

• DC-Text: A Text Syntax for Dublin Core Metadata

• Guidelines for using resource identifiers in Dublin Core metadata - DRAFT

Other work

• A summary of the current situation w.r.t. URIs for DCMI's XML schemas is available here with agreement being to move forward on the basis of proposal 1(b).

Published/stable documents and resources

• DCMI Abstract Model

• Expressing Simple Dublin Core in RDF/XML
