Add discussion points to the agenda

[xuorig]

Adding two discussion points to the agenda.

They're both quite large subjects so I put 30m but feel free to scale that down to leave room for other subjects if needed 🙏

I know this has been discussed previously, feel free to remove it if you feel like this won't add much to the conversation 👍

Thanks!

Great, thanks a lot for adding this agenda topic, @xuorig! 👍 I was also thinking about adding it, should be an interesting discussion.

@xuorig It would be great to have a short description of both agenda items. I think it allows attendees to think about them beforehand so we will have a more productive discussion.
Having agenda items link to GitHub comments similar to previous agenda would be great.

Discuss exposing schema metadata

Do you mean something similar to graphql/graphql-spec#300 ?
Or you proposing to allow fully customizable introspection
as described here: https://github.com/rmosolgo/graphql-ruby/blob/1.8-dev/guides/schema/class_based_api.md#custom-introspection

@IvanGoncharov sure, good idea. I can add a bit of context here:

I'd like to be clear that I am adding these to the agenda to discuss potential solutions, not to propose one, so both links could be related. Issue #300 does talk a lot about the problem and is probably a good read before the work group meeting. Amongst other things, I'd like to discuss:

• Is the graphql schema the right place for exposing metadata? Should it live outside the schema?
• extending the introspection schema & custom Internal types __MyCustomMetadata
• IDL vs JSON introspection
• "global" metadata vs member metadata
• directive limitations

For the errors point, I'd like to discuss a few points:

• Using "client errors" (Defined in the schema) for mutations vs the spec's "errors" key.
• Limitations to common client errors implementations.
• Potential additions to the errors spec

(I can also talk about our specific use cases at the meeting.)
