While there are general caveats to think in terms of a declarative language instead of a procedural language, I think Adam's query is just fine. On bit is that to remain SPARQL compliant, you should use BIND. I.e.: BIND (IF( ?aVal > ?bVal, "conditionaltest:PersonTypeA","conditionaltest:PersonTypeB") AS ?type)
