Hi all, I am still trying to make spatial searches in Jena but it seems Jena doesn't find my spatial index. I use an assembler file to configure a TDB dataset and a spatial index, load the data into TDB, start the indexing and then start Fuseki but when I make a SPARQL query Fuseki retuns an empty result and logs the following message WARN Failed to find the spatial index : tried context and as a spatial-enabled dataset In the dataset only geo:lat and geo:long properties are used (no WKT) to make things simple. The assembler file is available at the url http://www.sharesemantics.com/test/jena/jena-spatial-assembler.ttl while the dataset (24 triples) is available at http://www.sharesemantics.com/test/jena/spatial-data-latlong.ttl I upload the dataset into TDB using the command $tdbloader --desc jena-spatial-assembler.ttl spatial-data-latlong.ttl In the assembler file the directory of the spatial index is set as a local folder and I can see that the files in the folder are updated when I run the indexer with the command $java jena.spatialindexer --desc=jena-spatial-assembler.ttl The indexer writes the following message when it's done $INFO 24 (24 per second) properties indexed So everything seems to work fine till this point then I start Fuseki using the same assembler file java -Xmx8G -jar fuseki-server.jar --port=2020 --desc=/home/luigi/jena/apache-jena-2.11.1/jena-spatial-assembler.ttl /fusepoolp3 and try to make a simple query (suggested by Andy in a previous email) PREFIX spatial: <http://jena.apache.org/spatial#>SELECT * { ?place spatial:nearby (51.38 -2.7 10 'km') .} but it doesn't return any triple even if the Bristol International Airport is close to the location given in the query and Fuseky writes the following message WARN Failed to find the spatial index : tried context and as a spatial-enabled datasetWARN No text index - no text search performed I didn't configure a text index as it should not be necessary as far as I know. My questions are the following: 1) why Fuseki can't find the spatial index 2) which is the purpose of the following definition that must be written in the assembler file ( as stated in Jena Spatial documentation )<#definition> a spatial:EntityDefinition ; spatial:entityField "uri" ; spatial:geoField "geo" ; Thanks to anyone who can solve this issue Luigi
