Possibility of integrating OWL2 Reasoner and GeoSPARQL?

[gpicciuca]

Hello,
I'm evaluating whether Tentris would be a good pick for a project my company is working on as we're looking for a Knowledge-Graph solution with semantic reasoning/inference capabilities and GeoSPARQL support.

As far as I could see, Tentris does not integrate reasoning/GeoSPARQL so far. Thus, I'm wondering if there would be any chance if this could be implemented by you or, if possible, could give us some guideline on how to do it ourselves and eventually contribute to your project.

Lastly, are there any benchmarks for Tentris?

Thank you

Hi sorry for the long delay.

We do not plan to integrate reasoning or GeoSPARQL here at the moment. But contributions are always welcome.
For both, a good starting point would be looking at how the query library in hypertrie works. reasoning and GeoSPARQL should be implemented as an extended version of that library.
