this is a great report. Thanks for putting it together.

I have some corrections regarding our "Wilbur" toolkit:

First, "Lisp" is not an actual programming language per se. You should say
"Common Lisp" (this is the ANSI X3J13 Standard). There are other dialects,
such as "Scheme", but I haven't seen any RDF software for those.

We don't actually do releases, but label source code in the CVS. The latest
such "release" is labeled "just-before-Wilbur2-branch", and dated November
28, 2004. Fairly recent, that is.

As for the API paradigms, we support both a statement-centric view as well
as a resource-centric view.

"Wilbur 2" is in the works, and will probably be released in a month or so.
It has, among other things, database support (anything CL-SQL supports,
theoretically anyway, that is MySQL, PostgreSQL, ODBC, etc.). It will also
have Ntriples serialization and parsing.

Kind regards,
