aboutEach alternative

Hi all,

I was wondering how te deal with the following in rdf:
I have multiple book-resources (cf. example; http://foo/book123456,
http://foo/book7891011) that are described using the same hasRights
property. The hasRights property of these resources always has the same
value; namely an xrml-XML segment. The XML fragment in its entirety
corresonds to one subject. How can I express the above-mentioned scenario
(i.e., multiple objects are described using the same property and subject)
in RDF.

I am aware of the fact that you can do this easily be means of the aboutEach
attribute; however due to some reasons (such as, interoperability with other
systems and implementation issues), we can not use this attribute in our
rdf-architecture.

An alternative proposition of how to deal with the problem is shown
here-below. However, as you might notice, in the thirth rdf:Description, the
rdf:nodeID and rdf:parseType are used together. This is not allowed
according to the current rdf-spec.

Does anyone know how to solve this issue in rdf?

thanks
jeroen
