Excellent questions. I have been pondering that since shortly before I posted on this topic. Having spent more time searching on CPAN (see my other responses and my UPDTES to my original posting), I have to say that everything I had hoped for and would like appears to, indeed, be there...and more. I am impressed that there are actually several different Semantic Web frameworks (e.g., RDF::Redland and RDF::Stanford, and a couple of others) that seem remarkably complete.

Now my only problem is that I can't get a single one of those larger frameworks to install successfully on my Windows XP machine.

I am relieved to see the very significant, deep, and complete support for the Semantic Web concept within Perl; but I am now just frustrated that I can't (yet) access it.

Thanks, so much for your response.
