Description

Hello,

I am the developer behind postgis-jena and rdf4j-postgis, both projects to develop further geospatial query capabilities beyond GeoSPARQL also including raster data support for Apache Jena and rdf4j respectively.

I found that your project integrates very well with rdf4j and experimented a bit to include the rdf4j extension with your native queries to POSTGIS. (everything still work in progress)

https://github.com/i3mainz/kiwi-postgis

Benefits would be: You could use a native Java implementation to process geospatial functions and for most queries could forward them to a POSTGIS backend if available (as you seem to already want to do with the GeoSPARQL extension)

Is this functionality of interest to your project?
