Re: GeoSparql example?

I ended up using a different form of the query.  I might have to revisit
the question to see if I can make it more performant, but I did get a
working solution.

Discreet Global Grid System?

Let's discuss this separately to see if we can get Apache Jena GeoSPARQL up
to GeoSPARQL 1.1 conformance in the near future. Maybe there are already
some contributions in the community that could be integrated into the
Apache project.

Re: GeoSparql example?

2023-12-02 Thread Nicholas Car 
Well no other system that we know of offers GeoSPARQL 1.1 support either as the 
new version really is very new!

Most of the examples in that documentation are fine for GeoSPARQL 1.0 as part 
of the update was just to make better documentation.

I don’t think it will be hard for Jena to support the majority of GeoSPARQL 
1.1. The hard bit is DGGS and that is called out as a separate conformance 
class for that reason. Most of the additions are minor: things like ensuring 
full Simple Features spatial relations calculations work.

Nick, we only support GeoSPARQL 1.0 at this point in time in the Jena
project with some extensions that predate the OGC effort.

GeoSPARQL 1.1 is now approved by the OGC and its specification document 
contains many more examples than GeoSPARQL 1.0:
