Sorry.  I meant define it. Don't publish it widely. But internally,  
this mapping is
what your code then uses to make it virtually part of the semantic web.

A 1998 article on it, updated in 2002, proposing a mapping:
"Relational Databases on the Semantic Web"
http://www.w3.org/DesignIssues/RDB-RDF.html
This points to python code (dbview.py) implementing the mapping.

Slides on the architecture buried in my BioIT talk from around slide  
16 on
http://www.w3.org/2005/Talks/0517-boit-tbl

There are quite a lot of implementations of this sort of thing out  
there now.
