It is clear that the value of rr:inverseExpression can't just be any old SQL expression, but it must be an expression that … “reverses” an RDF term into a SQL condition. But what *exactly* does that mean? I made an attempt at formalizing this: http://www.w3.org/2001/sw/rdb2rdf/r2rml/#inverse This subsection is now officially my least-favourite part of R2RML… This will probably need revision when ISSUE-35 is resolved, because it involves substitution of column *names* into a SQL template. Best, Richard
