Publish exposition format as an IETF standard

[beorn7]

Original issue: prometheus/prometheus#1361 :
"It would be interesting/good to write up the exposition format as an IETF RFC standard. This would allow more adoption by "traditional" companies since they can reference a standard for both implementation and marketing "We support metrics via RFC XXXX"."

This issue is for tracking the work done towards an IETF standard.
We need to solve the other exposition format issues to really finalize this.

You can assign this to me if you want.

This depends on #545 imo.

Hi,

Is there any progress on this topic?

We are currently hammering a draft out in https://docs.google.com/document/d/1TapRdI5Tu2e8AIqREtdv_C36t4GGsDQr64KixE-gWu8/edit

Feel free to comment, but please don't edit.

Seems like this is now what https://github.com/OpenObservability/OpenMetrics is doing, does it make sense to close this ticket?
