Could not load imported ontology: <http://purl.org/dc/terms/> #27
Description
I am using AML for a uni assignment where we had to create our own ontology "Donde esta la discoteca" and use tools to align them with an existing ontology of that domain.
I am using the AML v3.2 release.
For this i chose to use the music ontology (http://musicontology.com/specification/ & http://purl.org/ontology/mo/). Note that the ontology is half broken as some old re-directs don't seem to work anymore (motools/musicontology#13 among others), hence the "-fixup". So much for persistent URLs...
Nevertheless, even after fixing the mentioned Ontology imports, AML fails to load something as common as http://purl.org/dc/terms/.
See the log output below. Apparently it does not follow the redirect to actually get the ontology definition? See output line Encountered " <INTEGER> "302 "" at line 2, column 14.
Is that the issue here? I am a bit surprised that could be the issue since I thought this redirect pattern is common and also dc/terms is a really common ontology that is used.
What needs to be fixed here or what is the issue?
If you need I can provide you the ontologies.
