Hi Tim, it sounds like you are asking for something similar to D2RQ but for an XML web service. D2RQ represents a virtual RDF graph that is populated at query time. What you would need is a virtual RDF graph that reacts on incoming SPO queries by issuing web service calls.
Out of the box I don't see how our current platform supports such scenarios. There are, as you have figured out, SPARQLMotion mechanisms to call web services and convert their result into RDF, but these are just individual calls and what's missing is some way of triggering such scripts for all 8 combinations of SPO arguments. I need to think more about how this could work - definitely an interesting topic! > > 1. User starts TB/Ensemble and opens the Person ontology. > 2. User selects Person class > 3.

There is no way to trigger a specific SM script in response to a search and we have no plan to support that. > > A second scenario is: > > 1.

I have put a feature request for such SM scripts to our bug tracker. The only work-around right now is to create a static copy of your web service data (as a batch operation) and then to run your queries against that local copy. I am not sure whether this is feasible for you, and how frequently you would need to update that copy.
