Sure, you can use the "normal" SPIN API over any Jena Graph or Model, including those created by the AllegroGraph Jena API. Note that by default the queries will be executed using ARQ only, which means that it will not make use of any optimizations on the AG level. In order to do that, overload ARQFactory so that it returns AGQueryExecution objects if possible.
