Description of the issue

Since merging PR #616 Protégé fails to open the OEO. It stops working while trying to open OMO, see last line of this screenshot:

Protégé just hangs at this step, the only possibility is to force terminate Protégé.

Oh dear! It works for me without even pausing for a second :-(. Protege saves all the "special" problems for you @l-emele !

What happens if you go to http://purl.obolibrary.org/obo/omo.owl in a web browser? (You should get redirected to a file)

l-emele commented 3 years ago

My browser redirects to this URL: https://raw.githubusercontent.com/information-artifact-ontology/ontology-metadata/v2020-06-08/omo.owl The content in the browser look seems to be the correct owl file.

I also can't replicate your problem. When I try to open the ontology, everything works fine.

l-emele commented 3 years ago

I just did a test: On a local branch, I replaced in the oeo-shared.omn the URL http://purl.obolibrary.org/obo/omo.owl with the URL https://raw.githubusercontent.com/information-artifact-ontology/ontology-metadata/v2020-06-08/omo.owl. Protégé then starts and loads everything without problems.

So we can narrow down the problem that the redirect is causing the problem. Maybe because the original URL is a http, the redirected on a https?

l-emele commented 3 years ago

We had issues before with redirects, see #426.

jannahastings commented 3 years ago

I seem to remember something about some redirection problem in the OWL API that was fixed in a recent version. Just double checking which version of Protege you are using?

l-emele commented 3 years ago

I am currently using Version 5.5.0 Build beta-4.

According to https://protege.stanford.edu/products.php#desktop-protege, the latest version is 5.5.0 (without beta). I'll download now that version and test whether this causes the problem, too.

l-emele commented 3 years ago

Using version 5.5.0 (stable) solves the problem. I documented in https://github.com/OpenEnergyPlatform/ontology/wiki/Prot%C3%A9g%C3%A9 that this version should be used.

I'll close this issue now.
