Holger, I finally got jena (and fuseki) to build with the maven pom additions you provided for the spin library. I checked the resulting jena-fuseki-1.0.0-server.jar file and the spin modules are in it. I launched this with 'fuseki-server --update --mem /ds' and then loaded my models into it. Then I ran the query on it that works fine in composer. I am inclined to say that the result I get back is empty but it really looks like:
------- | res | ======= | | ------- which is suggestive that there is a single result but that it isn't in ?res. As before, Fuseki can see my spin functions but it seems like it still cannot execute them. I am wondering if I did something wrong because I did follow your instructions to the letter. Here is the query: prefix sp: <http://spinrdf.org/sp#> prefix afn: <http://jena.hpl.hp.com/ARQ/function#> prefix fn: <http://www.w3.org/2005/xpath-functions#> prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> prefix quantity: <http://qudt.org/vocab/quantity#> prefix skos: <http://www.w3.org/2004/02/skos/core#> prefix spin: <http://spinrdf.org/spin#> prefix act: <http://siemens.com/schemas/activity#> SELECT ?res WHERE {BIND (act:commonLabelURI("http://developer.runkeeper.com/healthgraph#Spinning";) AS ?res) .} where 'act:commonLabelURI' is the spin rule. I 'have' tried using TBL and will address that issue in the next posting.
