Hi, I'm working with Fuseki 1.0.1, and trying to configure jena spatial...
I've followed the docs at http://jena.apache.org/documentation/query/spatial-query.html#supported-geo-data-for-indexing-and-querying and this is my configuration file: ---- # Licensed under the terms of http://www.apache.org/licenses/LICENSE-2.0 ## Example of a TDB dataset published using Fuseki: persistent storage. @prefix : <#> . @prefix fuseki: <http://jena.apache.org/fuseki#> . @prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> . @prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> . @prefix tdb: <http://jena.hpl.hp.com/2008/tdb#> . @prefix ja: <http://jena.hpl.hp.com/2005/11/Assembler#> . @prefix spatial: <http://jena.apache.org/spatial#> .

(http://neotec.rc.unesp.br/resource/geodata) I've tried the following query: PREFIX spatial: <http://jena.apache.org/spatial#> PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#> SELECT ?placeName { ?place spatial:query (52.4539 -1.74803 10 'km') . ?place rdfs:label ?placeName } But no results are returned... even with some variations of the coordinates.. How can I know my configuration is working?? The logs are set to DEBUG, but I cant really see a problem... What should I look for in logs?? Cheers Rodrigo C.
