Proposed Resolution for Issue 42

We discussed issue 42 on the telcon today but did not resolve it at neither Richard
nor Enrico was on the call.

The WG seemed inclined to accept the proposal from Souri:
-- maintain data equivalence (allowing converting either way, without loss of info) => this can be done by DM 1) always generating schema triples and 2) skipping generation of triples for NULL values

We also discussed whether we needed to prove that a SPARQL query could be generated on the
RDF that was equivalent to a SQL query on the Relational data.  The feeling was that, if there was no
loss of information, then there would exist a SPARQL query that was equivalent to the SQL query.
Alexandre pointed us to some work he had done on this.  See minutes.

Richard, Enrico please reply to this mail and let the WG know if you can live with this proposal.
We should close this issue next Tuesday.
All the best, Ashok
