I'm pretty sure that GeoSPARQL isn't part of the default Fuseki distribution yet, only the text index is there as an extension. I think I mentioned it some time ago, but forgot to keep track of it: https://github.com/apache/jena/blob/main/jena-fuseki2/jena-fuseki-server/pom.xml Regarding the confusion, the TE wants to use GeoSPARQL features with `tdbquery`, but this doesn't work at the moment. Adding a `jena-geosparql` Uber Jar to the classpath or use tdbquery from the Fuseki fulljar (once `jena-geosparql` has been added) will at least make the functions and datatypes being registered and work: ``` java -cp /tmp/jena-fuseki-fulljar-4.9.0.jar tdb2.tdbquery --loc /tmp/tdb2 ' PREFIX geo: <http://www.opengis.net/ont/geosparql#> PREFIX geof: <http://www.opengis.net/def/function/geosparql/> PREFIX uom: <http://www.opengis.net/def/uom/OGC/1.0/> SELECT * { BIND("POINT(1.0 1.0)"^^geo:wktLiteral AS ?p1) BIND("POINT(2.0 2.0)"^^geo:wktLiteral AS ?p2) BIND(geof:distance(?p1, ?p2, uom:radian) AS ?d) }' 07:53:56 WARN system :: The “SIS_DATA” environment variable is not set. ------------------------------------------------------------------------------------ | p1 | p2 | d | ==================================================================================== | "POINT(1.0 1.0)"^^geo:wktLiteral | "POINT(2.0 2.0)"^^geo:wktLiteral | 0.024683e0 | ------------------------------------------------------------------------------------ ``` What does not work is probably using a `GeosparqlDataset` in an assembler file because from what I remember when looking at the code some time ago, `tdbquery` only considers a TDBDataset? So my guess once you added a full jar of `jena-geosparql` (needs Maven shade plugin), the GeoSPARQL functions will work because they are registered via service loader, but the spatial index I guess won't as this is part of the `GeosparqlDataset` which registers the index to the query context on initialization. -- This is an automated message from the Apache Git Service.
