Feature Request: Simplify dataset metadata JSON files for dataset creation or import

Overview of the Feature Request
Remove elements from the dataset creation json file that are superfluous

What kind of user is the feature intended for?
API User

What inspired the request?
JSON files are long, complex and intimidating for new users.

What existing behavior do you want changed?
Remove the need of the following attributes in the dataset JSON files :

• typeClass for metadata fields
• multiple for metadata fields
• displayName for metadatablocks

Are you thinking about creating a pull request for this feature?
Even if this would help increase APIs adoption, we have other priorities at the moment.

The issue does not name files, tests, or an entry point. Start by tracing the dataset creation and import API handling of metadata JSON, then compare the current and simplified examples. Done means the listed attributes can be omitted while the requested dataset creation or import behavior remains correct.
