Hellow again, Meanwhile I am doing a PoC to show our organisation what DataHub can do - working well. I have a question about ownership: Is it true “owners” can only be registered users with access to datahub? We have datasources from external companies - which we would like to mark as owner, but not grant access.

You don't need to have an existing account to be marked as a dataset owner. The owner will not have any details, just an urn. Until the actual user login and populate the information from oidc or something.

can I populate it through the api? Wondering because I could not find it.

You could populate things like the full name through the API yes. As long as you know how the urn looks like. Or use ldap ingestion to pre-populate the user details

Okay, many thanks - I’ll dig further to see how I can do this throuh the api

You can check out the corpuser definition here ( though I personally don't define it like this https://github.com/datahub-project/datahub/blob/master/metadata-ingestion/src/datahub/api/entities/corpuser/corpuser.py )

It works, thank you for pointing me to the right direction!
