   I expanded the minimal example to include geosparql information but it still 
did not work.

   @galbiston  I confirm that the `/path/for/database/` is the same in both of 
the following commands

   Am I missing something?
   
   @SimonBin thanks for your answer! I will keep it in mind for certain use 
cases. However, in this particular one, I am looking for an open-source 
triplestore with GeoSPARQL support (like Jena) to import ~50Milion triples to 
run GeoSPARQL queries offline as there is some health data involved. Any advice 
would be welcome.
   
   I would have preferred to use geosparql-fuseki for the full GeoSPARQL 
support but if it does not support named graphs I might try to use jena-fuseki 
with GeoSPARQL enabled. Is there a ready to use fuseki server with GeoSPARQL 
enabled?
