Staged demonstrators

Hi Team
 
Based on the plenary last week, I have a proposal about the first
demonstrator. I think it would be possible to build a demonstrator quite
quickly, based on the OCLC demo, that tries to solve the same problem of
using RDF to interoperate between different vocabularies. In OCLC demo the
mapping between different vocabularies is mainly done using custom code. The
big difference between the demo and the OCLC version is it would use a
persistant store. For more details see the diagram below:
 

 
The next step would to refine / refactor this to use schemas or ontologies
to map between different vocabularies, and use a query processor (RDQL) to
query the persistant store. This is shown in the diagram below:
 

 
Finally, the complete system would demonstrate tools for creating the
various declarative descriptions used by the system. It would also provide a
registry to manage different schemas as shown in the diagram below.
 

 
So my questions are:
 
- do these diagrams look reasonable (the Visio diagrams are in the
IPSSources CVS if you want to edit them)?
 
- if so, does the team thing it is a worthwhile exercise to try to put a
very limited prototype as described in the first diagram, say over the next
month? 
 
kind regards,
