Remove identifier from metadata

We decided that we do not need identifier in the metadata. At the moment it is required. To phase it out without breaking all currently working metadata, we should make it non-mandatory, but allow including it. Subsequently, we can remove it from our index and stop showing it in the front-end.

We could send a deprecation warning, but this would require some changes to the validation logic, since we currently only send emails when metadata is not accepted.

changed milestone to %2022 Februar Sprint

added metadata label

mentioned in issue #260 (closed)

added medium Priority label

The filehooks code can now handle a missing identifier and still accepts this field, but no deprecation warning is sent when someone includes the identifier.

Gitsearch still shows the identifier when it is present but can also handle its absence.

potential TODOs:

• remove identifier from gitsearch
• send deprecation warning for metadata including identifier
