Problem: API Key is not optional for Dataverse storage spaces when it can be made optional for open access Dataverses

[ross-spencer]

Please describe the problem you'd like to be solved.

Archivematica can connect to any open Dataverse, but setting up a storage space requires an API key. This should be considered an optional field only required when restricted datasets are desired.

Describe the solution you'd like to see implemented.

Make the field optional.

Describe alternatives you've considered.

There isn't a workaround for this at the moment as the API key will be checked by Dataverse if it is there.

Todo: Double check the versions (or at all if this is possible) as for a 4.3 endpoint, https://datasets.socialhistory.org/ I am receiving the following message:

For the SP demo Dataverse setup as 4.8.6 I see the following successful response without an API key:

archivematica-storage-service_1  | DEBUG     2018-10-12 21:06:24  locations.models.dataverse:dataverse:_browse_dataverse:140:  URL: https://demodv.scholarsportal.info/api/search/, params: {'q': 'sample', 'sort': 'name', 'start': 0, 'per_page': 50, 'show_entity_ids': True, 'type': 'dataset', 'subtree': None, 'order': 'asc'}

So this may be a configuration option for Dataverse administrators.
