Windows paths are not handled properly

[CasperWA]

From CIF-ontology, I tried to run generate_cif.py locally on my Windows 10 environment with Python 3.8.

First, an issue arised with Windows paths for the PyCIFRW dependency, which has been reported and subsequently fixed.
When running the script now, it fails for similar reasons (Windows path handling) via the this dependency, specifically in the line self.top = self.world.get_ontology(cif_top).load(), where self.world = emmo.World().

Full traceback:

C:\Users\c_w_a\Documents\GitHub\CIF-ontology\cif_top.ttl does not look like a valid URI, trying to serialize this will break.

My setup:
Windows 10 (version 20H2, build 19042.928)
Python 3.8.1
Virtual environment through virtualenvironment-powershell.
Installed EMMO from PyPI (version 1.0.0)

While I normally use WSL 2.0 (Linux kernel in Windows), I would prefer not to for this particular project.

Actually, it looks like the issue is the rdflib package.

Hmm, it might be my fault for working in the branch, where I moved stuff around and the fact that the script expects the ontology files to be present alongside it.

Indeed. This could all be fixed from the side of the script using EMMO-Python, i.e., it should be fine on this side. I will therefore close this issue.
