Thank you for establishing this. It will make things easier.

Your argument hinges on a claim that one proposal is correct, and another is incorrect. Can you state the criteria that an RDB2RDF mapping has to fulfill so that you consider it correct and complete?

Thanks,
Richard

That is not unusual -- many people here haven't, and to the best of my knowledge NO ONE here has read the SQL spec. That's why I asked and offered a walkthrough. You said you don't need that because you were in the SPARQL WG. That's a non sequitur. Many members of the SPARQL WG have not read it either. I did not intend this question as a personal attack, and if you took it as one then I have spoken poorly. However I explicitly question whether one can make statements about the formal correctness and completeness of RDB-to-RDF mappings without being aware of the model-theoretic semantics of RDF.
