Regarding person relationships see page 19 of the documentation. The
RDF data certainly is less specific than the the underlying data.
Family relationships seem to be explicitely encoded but for other
kinds of relationships only the general rdaRelGr2:relatedPersonPerson
is used.

To get a feeling for the underlying data take a look at
<http://gso.gbv.de/DB=2.1/PPNSET?PPN=133840107/SET=6/TTL=1/PRS=PP/NXT>
(That's the corresponding authority record in the GBV union catalog in
Pica+ format.)

I don't know whether there is a controlled vocabulary behind this
practice of typing a relationship but I guess there isn't. (Any people
familiar with German cataloging on this list?) But there will at least
be a common practice for this.

All the best
Adrian
