licence does not work with metadata

This is because license is defined, and not licence. Should be possible to use both american and british spelling I think

The spelling depends on the ontology. I guess that you are using Dublin Core terms (http://purl.org/dc/terms/) which uses english spelling.

No, I was using an EMMObased-ontology, so it is defined from there. My suggestions was only to have a check for if we licence is written in metadata it will be changed to license if that is defined. And if tou search for licence in metadata it will give the license if that is defined and not licence. But it is a picky thing, maybe not so important?

[jesper-friis]

I see. I think that we should leave it to the ontology to add language support, rather than doing it in EMMO-python. What happens if you add the American spelling to the license annotation attribute?

Ok, then I will close this issue.
