@sijie how can I find that proposal? link?

[sijie]

for people who are interested in this topic, here is the proposal : https://github.com/cloudevents/spec/pull/237/files

The proposal was a bit old. I think the CloudEvents has evolved to 1.0. So the proposal might need to be reworked to 1.0 specification.

I think this would be a great contribution.

I'm interested in this. We're taking a serious look at CloudEvents.
