However, using a prefix (e.g. FILTER <bif:st_intersects>) is where angle brackets should not be used. Yes that's correct - the prefix defines a resource (node) already.  I.e. given the above prefix definition, the following are the same URI:   bif:st_intersects   <http://www.openlinksw.com/schemas/bif#st_intersects> ...however, the original statement was "the rule I execute is working under TBC Sparql tab".  Now that David points this out, I'm not sure how that is possible (?)  The "no registered function factory" warning should occur and not results will be found. -- Scott On 1/7/2015 2:06 PM, David Price wrote: Only use angle brackets for full URIs, not when using prefixes.

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?
