You can test your endpoint with this tool (View->Show endpoint bar and write the url of your endpoint).

@Smalyshev I have not proxy (I masked my address)

Hello
I developed a filter of my side for removing the problems in the ttl.

@Smalyshev
My problem : I cannot load the ttl of wikidata with a request LOAD when there are triples about GeoSparql :

GeoSPARQL is a standard of OGC and not of W3C. Wikidata needs to do the difference between the lobbies and the recommendation of Web. I read in the documentation of this standard of OGC.
http://www.opengeospatial.org/standards/geosparql

@Smalyshev
I can test incompatibility of types with the triple stores on the market, if you want help all the editors to be compatible with Geosparql. But a quick solution is to create a filter of your side and hide these exotic triples for basic developer (like me) so I will deploy easily an core Wikidata and share compatible queries with the community.
