Re: Bi-directional mapping (RDF2RDB)

Ashok, All,

Let me clarify my position here: it should of course go into the XG report
as to not 'lose' any of our thoughts here; however, maybe it is wiser not to
push it too far and directly put it into the charter, yes, here we seem to
agree.

Cheers,
Michael
