Multilanguage Publisher and Contact Point

[kronmar]

Is your enhancement related to a problem? Please describe. https://int.visualize.admin.ch/en/v/o3i1aYPapuz5

This cube has dcterms:publisher in four + one languages: https://s.zazuko.com/3f8D5zh. None of them are displayed. Unlike title or description of the cube, the publisher can't be multi language at the moment.

Describe the solution you'd like Here is the line where a multi-language support should be handled. I feel, that the publisher/source should be able to change depending on language as well.

Additional context The same issue with the contact point on visualize. The cube has four languages + one for the contact point's vcard:fn. Instead of any of the names, visualize only displays the e-mail adress.
