@satra - can you take a look

I'm having problem with jsonld playground when uploading reproschema.jsonld because of this line
Perhaps I can remove it, since it shouldn't be there anything that it is not already in our context, but I also don't have any error when I parse the file using rdflib

@djarecka
I checked the generated files and they would still raise linting errors (for example line length errors due to long strings...), so I think we should not bother with linting / formatting auto-generated files.

I don't think it matters for now, we can update the linting config after this is merged.

so do we need a yes from @satra for this one? or we can merge it

[yibeichan]

@djarecka aha, so would you like to add a note to README.md about how we do this fancy (GA) release?
after contributor section, we can have a Developer Note about how we do release and everything.

i will close this now and create another one after merging #500 to be sure that we haven't forget anything
