[fhennig]

As was discussed earlier, here are the code places marked where I think changes will be introduced to implement this feature.

@corneliusroemer you wanted to have a look first. Putting this on hold till then.

Would the backend not need any changes?

[fhennig]

That wasn't in the ticket I think. But maybe that was a mistake? I remember that we talked about that too actually. I'd be curious to look into how to do that

[theosanderson]

My guess (maybe wrong) of what would happen if you made the changes annotated would be:

• backend would still expect data use terms on submission so would give an error
• backend would still emit data use terms in get-released-data so SILO would get confused at the unexpected field

[chaoran-chen]

We need to do some changes so that (1) the backend accepts submissions that don't provide a data use term and (2) don't expose it in get-released-data. But if it make things easier, it could write "open" into the database.

[fhennig]

Ah, makes sense

[fhennig]

that should cover it.
