Display of keywords in OJS 3.0.2.0

Hi two questions

1. So do you plan to keep both the subject and keywords fields in the metadata? And if so, what is the plan with they keywords field? I mean, when should that be used and will it show somehow show in the exported metadata, for example in DC?

I am planning to connect a thesaurus service to OJS (Finto) and I am trying to figure out what field it should be that I connect it to.

2. $article->getLocalizedSubject() should probably be edited so that it is not using the submission_settings field anymore?
