I think the recent discussions about RDF and the CRM go well beyond just
offering criticism.  You'll find the document which I started on Google


which is an attempt at a self-contained 'how to' guide for CRM RDF
implementers, and which reflects the recent discussions on this topic.
I'm happy to develop this document further, and would welcome input from
others on this list.  Conversely, if this document doesn't meet a real
need, I would be equally happy to be told why this is the case.

Best wishes,
