Hi all, I'm enjoying experimenting SPIN rules as federated queries to Linked Data cloud and local Virtuoso stored datasets. The queries I'm trying to implement in SPIN are CONSTRUCT with bif: geospatial functions usage. I have tried this in TBC FE 4.6 but I get a strange behaviour:
the rule I execute is working under TBC Sparql tab (even if raising "- URI <bif:st_point> has no registered function factory" warnings) producing the expected inference outcome. If I try to execute the same as a spin:rule attached to a class with Run Inference I get no results, also Im unable to add the row *PREFIX* bif: <http://www.openlinksw.com/schemas/bif#> to the rule, this is being deleted after clicking enter. Query is like: CONSTRUCT { ?this owl:sameAs ?that . } WHERE { ?this foaf:name ?label1 . ?this geo:lat ?lat1 . ?this geo:long ?long1 . SERVICE <http://194.119.214.82:8891/sparql> { GRAPH <http://localhost:8891/open-data-trapani> { ?that <http://any23.org/tmp-musei/Nome> ?label2 . ?that <http://any23.org/tmp-musei/Latitudine> ?lat2 . ?that <http://any23.org/tmp-musei/Longitudine> ?long2 . } . FILTER <bif:st_intersects>(<bif:st_point>(xsd:float(?lat1), xsd:float(?long1)), <bif:st_point>(xsd:float(?lat2), xsd:float(?long2)), 0.08) . } . } * Any suggestion?* *Thanks* *Antonino Lo Bue* *CNR-ICAR Palermo* -- You received this message because you are subscribed to the Google Group "TopBraid Suite Users", the topics of which include Enterprise Vocabulary Network (EVN), Reference Data Manager (RDM), TopBraid Composer, TopBraid Live, TopBraid Insight, SPARQLMotion, SPARQL Web Pages and SPIN.
