Neubert,

(I copy this to the RDFa task force mailing list, too, because this may
become a nice example for the usage of RDFa, too!)

I am sure that others will have comments on the versioning, URI choice,
etc. But I just spotted a small bug on your RDFa encoding of the pages.

In, eg,

http://www.zbw.eu/beta/stw/versions/test/thsys/090858891/about.en.html

you use the RDFa @about attribute with:

@about="stw:thsys/090858891"

however, according to the RDFa spec, the value of @about should be a
'safe' Curie. Ie, either you should put in the full URI, like:

@about="http://www.zbw.eu/beta/stw/thsys/090858891"

or you can say:

@about="[stw:thsys/090858891]"

the present setup will generate, in RDF/XML,

<stw:Thsys rdf:about="stw:thsys/090858891">

which, well, looks like using a different URI scheme...

Cheers and thanks!

Ivan
