Jos,

The version of Euler that produces swap/reason proofs...
is that released?

I tried my euler install last night, and it's lightning
fast, but it doesn't have all the built-ins I need.
In particular, I added support for fn:resolve-uri
and fn:tokenize from XQuery to cwm this week.

I also wonder if it would solve some performance
problems we're having in the PAW project.

You did some work in python, yes? Is that working well?
Or would you recommend the Java or C# version? or prolog?
Or javascript?


I'm not sure what version of Euler I have:

$ md5sum ~/DIST/Euler.zip

I'm working on rules for GRDDL; see
http://www.w3.org/2004/01/rdxh/spec
http://www.w3.org/2004/01/rdxh/grddl-rules3.n3

cwm finds 3 solutions where Euler finds just 1...
