I'd love the ability to specify the version of a schema.
It should identify the version of the current schema (not of the specification/meta-schema.
It should be recommended to use semantic versioning of the schema.
Similar to OpenAPI info_object.version: https://spec.openapis.org/oas/latest.html#info-object
It would help to express openEHR archetype models for clinical data in something standard like json-schema.

It could be solve by introducing a new keyword like "version" where the value is a string with recommended formatting in "x.x.x".

p.s. I'm sorry if this has been asked and answered. a search for 'version' produced many results, the first two pages were not relevant and 'semantic version' didn't produce any relevant results.
