If you are interested in SKOS / SKOS-XL manipulation, I can suggest this:

http://art.uniroma2.it/owlart/

to use SKOS/SKOSXL features, you need to download the latest sources from
the main-trunk of the project site on google code (last stable binary
release does not include SKOS/SKOSXL) :

http://code.google.com/p/owlart/source/checkout

these API provide interfaces over existing triple store technologies and we
use them as an RDF abstraction layer in our SemWeb tools. The sole
distributed wrapper is for the Sesame2 triple store
(http://code.google.com/p/owlart-sesame2/, again, get them from the source),
though we built others (Jena, Allegrograph, Protégé etc...) in the past and
can provide the sources if u need em.

The provided vocabulary interfaces are for RDF/RDFS/OWL(1) [though they do
not have direct methods for specifying restrictions] and SKOS/SKOS-XL
vocabularies, and there is support for named graphs.

Documentation is still...none :-), except for the javadocs, but from the
unit tests you can easily get some example, or ask me in case of need.

Hope they meet your requirements,

cheers,

Armando
