DCMI Architecture Forum Issues

Noticed on 2009-08-27

In thread Discussions > Google Search Appliance/Google Mini > Filtering on Dublin Core metadata possible?:

http://www.google.com/enterprise/search/mini.html

We've run into the same problem. Our institution uses GSA V5.2. We've modified the separator from a dot to a dash (e.g. DC-creator instead of DC.creator). In our tests, we've found that both the dot and colon are parsed incorrectly by the GSA in metadata searches. The dash however, seems to function.

as of 2008-07-02

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.
