I will look at it again. Is there an open source implementation by the
way? I have been using SPARQL CONSTRUCT queries to do virtually
everything that I thought SPIN could do, with a more familiar
notation. I didn't find the SPIN notation easy to understand.
Yes, the way SPARQL is formulated with RDF might be turn out to be a bit too
complex.
They have an open source reference implementation built on the Jena API:

Never tried using so far, though.
Cheers,
