Ensure we have a working API

Ensure the API is in sync with the user interface and deposit requirements

@cc-a I am unclear on what needs to be done.

Is it to bring the REST API in sync with the customizations done on submission form?

That is to say:

• for the REST API not to recognise a creator having a role?
• for the default values of publisher and resource type to be the only acceptable ones (this could be achieved by making resource type a vocabulary of one item)?
• for the acceptable values for rights just to from the fixed list?

Hey @J4bbi, yep. In addition to the items you list above we should also prevent setting references or publication_date metadata via API.
