Hi Andy,
Many thanks for your support.

I cloned Jena repo and I’m now looking at the jena-arq-examples module, thanks.

I'm still clueless about how to configure Jena for textual AND spatial
indexes.
I tried yet another assembler file:

but even less good as

Get it working with a query string in your program exactly like the
tutorial.
You have a graph name of

in the data. The relative URIs will be resolved to absolute ones.
Try using

Hi Andy, will the GeoSPARQL implementation be available before the jena-spatial
module is retired?

Hi Jean-Marc,
The WGS84 Lat/Lon isn't part of the GeoSPARQL standard.
However, I'm looking into supporting them in the replacement module.
For example:
- converting WGS84 datasets to GeoSPARQL format.
- SPARQL function for conversion of WGS84 to WKT Point in query (making
the GeoSPARQL
Greg , this looks nice,
and when you need a tester , I can test .

Semantic Web,
Especially, having atomic properties like oldgeo:long and lat , having well
