I would just like to chime in a bit from the side here: If I remember 
correctly, XMP is also RDF/XML, but a very archaic form of an old 
RDF/XML spec, whereas SKOS is a state-of-the-art application of 
Semantic Web technologies. Thus, it doesn't need to be a high degree of 
conflict between using SKOS and XMP, but I think that one will find 
that XMP is inflexible in a relatively short term, and while SKOS isn't 
widely deployed yet (I have application based on it though), it is 
reason to think that it will see wider adoption than XMP in the longer 
term.
