[francescalb]

This works for me now in both windows and linux.
from ontopy import get_ontology
onto = get_ontology('https://raw.githubusercontent.com/BIG-MAP/BattINFO/master/battinfo.ttl').load()**

Can you please check?

Wouldn't this create other issues, since the URL is now not normalized?

Both Jesper and I tried to see if we found such cases, but did not. The reason why it was commented out and not deleted completely was for easy reversal (and then searching for a new solution for Windows) if needed.

Yes, I do to on windows. We need to set up a testing environment for windows. Since I (almost) never use windows for this I have not encoutnered them. I suggest making a separate issue for creating a windows testing environment though. And we just make sure that loading works in both windows and linux for now

On a fresh installation (new virtual environment and clean repository clone), the correction seems to work as test_load is working, the error present in master v0.3.1-19-g02b3c84 (FAILED test_load.py::test_load - urllib.error.HTTPError: HTTP Error 400: https://raw.githubusercontent.com/%5CBIG-MAP) does not appear anymore.
