Hi Gill,
You've got the right idea. Try this instead:
<rdf:RDF xmlns:rdf="
http://www.w3.org/1999/02/22-rdf-syntax-ns#";
xmlns:rdfs="http://www.w3.org/2000/01/rdf-schema#";
xmlns:fedora=
"info:fedora/fedora-system:def/relations-external#">
<rdf:Description rdf:about=
"info:fedora/[PIDofThisObject]">
<fedora:isMemberOfCollection
rdf:resource="info:fedora/nls:100"/>
<fedora:isMemberOfCollection
rdf:resource="info:fedora/nls:101"/>
</rdf:Description>
</rdf:RDF>
This is actually equivalent in meaning to the RDF you posted (which itself
is valid RDF), but RELS-EXT is more constrained than generic RDF: it only
expects a single rdf:Description element because the subject (the thing
you're making statements about) is the same for all statements expressed
within a RELS-EXT datastream.
