Starting in the afternoon of February 6th, 2025, the CMA will support marking taxonomy validations as required on content type metadata.

Once a particular taxonomy validation has been marked required for a given content type, any entry of that content type will be checked on publish to determine if the entry has taxonomy concepts assigned which fulfill the required validation(s) from the relevant content type.

To make use of this feature, a new required boolean property on the link to the taxonomy concept or concept scheme can be sent in POST, PUT, and PATCH requests for content types.

Once the feature is live, this new property will always be returned on the content type and defaulted to false.

Documentation for the Content Type endpoint can be found here
