Can metadata information be included in the introspection query?

[gjtorikian]

I admit I haven't looked into the spec or the code much, but: one can define metadata definitions for new properties on GraphQL items. Could this be exposed in the introspection query?

I think it'd be neat for tooling cough https://github.com/gjtorikian/graphql-docs cough to be able to represent this information. I am not sure if the use case is so narrow that it doesn't apply, and that's fine. I just want to open a discussion to see if it makes sense.

The spec makes no mention of extending the introspection types: https://facebook.github.io/graphql/#sec-Schema-Introspection

I'm open to supporting extending those types, but I don't have much of an idea how to do it.

One way to do it might be, when IDL-to-Schema support is better ( #727 ), is to allow overrides of the built-in introspection types in the IDL, then use user-provided behaviors to resolve them.

I'm trying to support this in 1.8 via #1170, does that look like it would do the job?

I'm not sure. It seems that the community is still deciding on what a metadata format should look like (graphql/graphql-spec#300) so jumping ahead and defining a format for that might not be the best. As @xuorig mentioned in another thread:

Given that no 3rd party tools can use this information right now since it breaks the spec, it almost seems like the only users would be ourselves.

This is possible in GraphQL-Ruby now, we can track spec changes on the above-mentioned issue
