Hi Axel:
The proposal is that RIF be one possible syntax for the mapping 
language, not the only syntax, correct?

Seems reasonable.  A rule consists of 2 parts and in our case the parts 
may be, say, the name of an OWL class and the SQL query that can be used 
to query that class,

All the best, Ashok
