What is the best way to define custom metadata for tabular resources?

[augusto-herrmann]

When I need to define custom metadata for a resource, I could use Profiles and define a custom JSON Schema profile for the Resource. However, since it's no longer a Tabular Data Resource, tools like Good Tables will no longer validate field types in columns and other restrictions on data that are so useful to automate.

Is there a way to define custom metadata for tabular resources, while still maintaining tool compatibility with tools that handle Table Schemas?
