Some metadata is missing from your schema. What can I do?

Your first step is to suggest it on the forums or mailing list by sending us your use case.

This allows others to provide input to ensure the metadata is added in the most appropriate location so it can work in all cases. From there it will progress to a ticket on the Trac and after research to find the most general name for the term it can get rolled into the next schema release.

In the short term it is also possible to use StructuredAnnotations to store the value into the existing schema.
