Re: [oXygen-user] [OXYGEN-6052] Why is the JSON Schema $anchor not supported?
Hi Roger, Thank you very much for the feedback. We use a third-party library for JSON Schema validation and, unfortunately, it does not support the "$anchor" and "$dynamicAnchor" keywords. This is mentioned as a limitation in our user-guide <https://www.oxygenxml.com/doc/versions/25.1/ug-editor/topics/json-validating-json-schema.html#json-validating-json-schema__section_n4d_llf_y5b>, but, indeed, the message displayed for "$anchor" is not accurate at all. We plan to provide full support for JSON Schema /Draft 2020-12/ in the near future by using another library. I will let you know when this support is ready.

When I add "$anchor" to my JSON Schema, the Oxygen editor gives this error message:
The keyword "$anchor" is not part of JSON Schema Draft 2020-12 specification. Therefore, it is ignored by the validation engine.
But that's not true. See section 8.2.2 of the 2020-12 specification (https://json-schema.org/draft/2020-12/json-schema-core.html#section-8.2.2):
Using JSON Pointer fragments requires knowledge of the structure of the schema. When writing schema documents with the intention to provide re-usable schemas, it may be preferable to use a plain name fragment that is not tied to any particular structural location. This allows a subschema to be relocated without requiring JSON Pointer references to be updated.
The "$anchor" and "$dynamicAnchor" keywords are used to specify such fragments. They are identifier keywords that can only be used to create plain name fragments, rather than absolute URIs as seen with "$id"... _______________________________________________ oXygen-user mailing list oXygen-user@oxygenxml.com https://www.oxygenxml.com/mailman/listinfo/oxygen-user

Would you mind telling me what library (JSON Schema validator tool) that you will be adding into Oxygen?
