The proof resulting from
eye http://www.w3.org/2001/tag/dj9/badmeta.n3 
http://www.w3.org/2001/tag/dj9/speech.n3 
http://www.w3.org/2001/tag/dj9/httpspeech.n3 
http://www.w3.org/2001/tag/dj9/time.n3 
http://www.w3.org/2001/tag/dj9/owl2.n3 
http://www.w3.org/2000/10/swap/util/owlth.n3 
http://www.w3.org/2000/10/swap/util/rdfs-nice.n3 --query 
http://www.w3.org/2001/tag/dj9/contradiction.n3
is attached as att1.txt and the check --report is attached as att2.txt

and the latter is not happy with the "bnode to univar rewriting in the 
rule premis"
so I tested with manually rewritten rule premises and the proof resulting 
from
eye http://eulersharp.sourceforge.net/2007/07test/badmeta.n3 
http://eulersharp.sourceforge.net/2007/07test/speech.n3 
http://eulersharp.sourceforge.net/2007/07test/httpspeech.n3

http://eulersharp.sourceforge.net/2007/07test/owlth.n3 
http://eulersharp.sourceforge.net/2007/07test/rdfs-nice.n3 --query 
http://eulersharp.sourceforge.net/2007/07test/contradiction.n3
is attached as att3.txt and the check --report is attached as att4.txt

and the latter is now happy :)
I also had to add the string search builtin in Eye and I see that it
is called "scrape" in http://www.w3.org/2000/10/swap/doc/CwmBuiltins

Yes, and this morning when I woke up ut was still running
jdroo    18976 99.9 55.2 1145392 1142316 pts/0 R+   00:19 610:58 python 
/home/jdroo/acasvn/wopeg/cwm/swap/cwm.py 
http://www.w3.org/2001/tag/dj9/badmeta.n3 ...

which is more than 10 hours..
This is however an old version of cwm and now I am testing with the latest 
CVS
version and that is indeed below 10 sec, waw, what a big difference!
