Open questions:

• is tooltip-based approach a right call?
• should we make URL a bit more flexible and allow it to be, say, a callback? it might make routing easier in the future.
• how would the Studio integration look like?

[lottamus]

Could just do a simple inline "(go to ref)" like we had in Next?

Clicking "(go to ref)" could emit JsonSchemaEditorStoreEvents.GoToRef or something and let the consumer handle it however.

Studio can listen to that event:

• If the $ref is local to the project, we can look up a Model node that matches the given URI, and set it as the active node.
• If the $ref is absolute or a url, we can attempt to open it in the browser.

I agree with @lottamus - what do you think @P0lip?

Already implemented in https://github.com/stoplightio/json-schema-editor/pull/24
Shall we apply the same change to JSV?

Shall we apply the same change to JSV?

Yeah I'd say so. But if we're showing a $ref in JSV it's likely because we couldn't resolve it so its unlikely that the $ref even exists
