I've incorporated these ideas in another simple registry prototype to help
illustrate the functionality and shape future requirements of the DCMI
registry system.
For example:
http://potlach.org:8000/view?subject=http%3a//purl.org/dc/dcmitype/Resource
http://potlach.org:8000/view?subject=http%3a//purl.org/dc/elements/1.1/relation
Using this as a debugging tool interestingly enough in the context of
http://potlach.org:8000/view?subject=http%3a//purl.org/dc/elements/1.1/relation
shows some inconsistencies in the http://purl.org/dc/terms/ declarations.
In http://purl.org/dc/terms/ all of the uri's have to be fully qualified, so
<rdf:Description rdf:about="http://purl.org/dc/elements/1.1/identifier">
<rdfs:range rdf:resource="IdentifierScheme" />
</rdf:Description>
should be changed to
<rdf:Description rdf:about="http://purl.org/dc/elements/1.1/identifier">
<rdfs:range rdf:resource="http://purl.org/dc/terms/IdentifierScheme" />
</rdf:Description>
This should be done for all of the relative URI declarations.
