SQL Table Value Functions are new to me. Let me see if I am with you.    (03)

Table Value Functions are generalized, updateable views using SQL procedures ?    (04)

-I have a RDB storing triples in a fixed schema and translating SPARQL
 queries to SQL    (05)

-I create a view using a Table Value Function with SPARQL in the function body    (06)

-I use SQL select/delete/update on that view like on a table    (07)

This is impressive. You have of course the performance penalty of RDF with
the performance penalty of RDF on top of a RDB but nethertheless: I am 
impressed.    (08)

I wonder if this works out in practice. Does anybody actually do this ?    (09)
