Events

[mnot]

I found this interesting:
https://blog.syncinc.so/events-not-webhooks

... and view it as potentially just a continuation / specialisation of work on feeds (e.g., Atom).

What do folks think? Worth spending time on some conventions here?

I think the feed space is in need of some evolution and standardization, yes. JSON Feed (and the discussion in manton/JSONFeed#49 especially) is worth having a look at. I know that EventStore uses Atom feeds as its data format and I've spoken to @gregoryyoung about their wish for it to evolve from XML to JSON.

We also have CloudEvents which aren't dealing with feeds, but are still relevant on the item/entry level which was standardized in RFC 4287 and probably should be evolved and provided in a JSON format too.

And I suppose we need to figure out how possible development in the feed space relates to Activity Streams as well?

API developers who provide webhooks (there are many), typically provide /events. It makes sense to work on this. +1

I would even suggest to incorporate CloudEvents as an envelope schema for these events in parity to https://github.com/cloudevents/spec/blob/v1.0.1/http-webhook.md.

[gregoryyoung]

So one question here would be whether or not a schema can be associated, if so is there some form of discovery mechanism?

[sdatspun2]

You mean https://github.com/cloudevents/spec/blob/v1.0.1/spec.md#dataschema?

[asbjornu]

What do you want discovery for, @gregoryyoung? The feed (of events) or its schema? The feed can be made available through the link relation alternate and its schema through the link relation service-desc, coupled with an appropriate type, exposed either in an RFC 8288 Link header, an HTML <link> element or similar.

[gregoryyoung]

will events that are incoming be validated against the schema or assumed to be fine?

[gregoryyoung]

said differently might I be able to type this?

I think it is definitely an interesting area, but there seem to be a number of efforts already ongoing. I'm not sure what value this group is would be looking to add. Would there be value in an link relation type for "events"?
