That's excellent news Tim, Dan, Sandro !!!
I love cwm :)

We're also pleased to announce that Guido Naudts
who wrote a masters thesis which can be found at
http://www.agfa.com/w3c/2002/02/thesis/thesis.pdf
(with stuff like the euler antilooping technique)
now also has his RDFEngine written in Python23 at
http://eulersharp.sourceforge.net/2004/02swap/RDFEngine/

There's some documentation at
http://eulersharp.sourceforge.net/2004/02swap/RDFEngine/readme.txt
and some test cases at
http://eulersharp.sourceforge.net/2004/02swap/testCases/
and a test release at
http://prdownloads.sourceforge.net/eulersharp/RDFEngine-1.0.0.zip?download

To get experience we now "swap" between
http://eulersharp.sourceforge.net/2004/01swap/
and
http://eulersharp.sourceforge.net/2004/02swap/
and
http://www.w3.org/2000/10/swap/
:)
