Is 1.0.0 the latest version?

To get the latest version of cwm, I did the following:

google 'cwm semantic web'
navigate to first hit www.w3.org/2000/10/swap/doc/cwm.html
navigate to 'Installation' http://www.w3.org/2000/10/swap/doc/CwmInstall
download http://www.w3.org/2000/10/swap/cwm.tar.gz

This got me a version that calls itself '1.0.0' and appears to have
been built in 2004.  Is this really the latest?

The reason I suspect it is because when I run it on one of my files I
get an error:

cwm ~/Scratch/out/medline07n0506/00/15548600.rdf  --n3 --pipe
 >15548600.n3
ValueError: This sink cannot accept datatyped values

referring apparently to this line

   <nc:starts-at rdf:datatype='http://www.w3.org/2001/
XMLSchema#int'>324</nc:starts-at>

which I suppose might be wrong in some way. Perhaps this is fixed in a
newer version, but I'm not sure how I could find that out.

Thanks
