Re: regd: geosparql query
Using GeoSPARQL with Fuseki requires using GeoSPARQL Fuseki module,
which runs Fuseki as an embedded server and has no GUI support. Please
see documentation at:
https://jena.apache.org/documentation/geosparql/geosparql-fuseki
I don't think the mailing list supports images so it's unclear what you
issue might be.

Not sure what exactly you're asking here. Maybe that's the point where
you should start with your whole use-case and workflow?
Otherwise, starting Fuseki with GeoSPARQL support is documented in the
first part of the docs:
https://jena.apache.org/documentation/geosparql/geosparql-fuseki
So why can't you start Fuseki from command line like explained there and
then use SPARQL HTTP protocol from within your Python code?

Hello, Thank you for the clarification.
I have another query, may be it is very simple question. I am sorry for
asking this. To run fuseki as an embedded server, is it only possible by
Java application ?? I am using python , so how that can be done?
as in the documentation they have addressed it as
"Run within a Java application to provide GeoSPARQL support over HTTP to
other applications:"
Thanks in advance,
Manoj
