But if it isn't possible to build a generic RDF engine then what benefit
are you getting from using RDF and not some proprietary encoding of the
information? David is trying to scope out what it means to write an RDF
engine: in other words what it means to achieve some economies of scale in
RDF software development.

What you seem to be saying here is analogous to: "SGML isn't too difficult
to implement. I made a tags and attributes language that looks like SGML
and can be expressed as an SGML subset. I wrote a parser in an afternoon
so SGML obviously isn't too difficult to implement."

As long as everyone writes their own engines for their own document types,
nobody is gaining any benefit from the standardization.
