Manually or broadly add optional behaviour to all attributes of all (or some classes).

AnyURL pydantic types are not json serializable, so urls are validated as str.

I've tried defining a custom json_encoder, but the pydantic type is not actually an AnyURL object, so I was not able to detect the right class.

A solution to this would properly leverage pydantic's url validation, but also allow for a successful json.dumps(<model>.dict()) of a class with a URI field.

When the UNTP publishes schema or vocabs, this library should import those by default to avoid required an unanchored vocab value.

Do you plan to licence this code?

a pydantic expression of spec-untp seems like a handy thing for python users, especially with all the first generation untp stuff happening in the js/ts ecosystem. But without an open source licence that’s compatible with people’s projects, they might be reluctant to use it (or contribute back).
