Mark,
I believe SPINMap may provide a good foundation and the custom bits for your
ontology can be added using SPIN functions. So in other words, if you can use
the built-in features of SPINMap for 90% of your mapping needs then you should
try to express the remaining bits using extension functions. You can model
those functions after the examples from the SPINMapL namespace - everything in
SPINMap is written in SPIN itself, i.e. no magic tricks or hard-coded stuff.
For complex scenarios where the design assumptions of SPINMap are not a good
match, you are free to add conventional SPARQL CONSTRUCT rules. From what I see
in your scenario, SPINMap plus a couple of extension functions may be a good
choice. But of course the devil may be in the detail...
HTH a bit - we can hopefully answer more in depth if you have specific
questions.
