Richard: I don't understand why the SPARQL engine needs access to the function. My model is that you map the data, then run the function, the functions transforms the RDF and then SPARQL is run on the transformed RDF.

It doesn't work if you want to SPARQL the output, because the function has to be available to the SPARQL engine (which is part of the R2RML processor). > > If it runs after the mapping, then it's outside of the R2RML implementation, so why talk about it in the spec. > > Best, > Richard
