WebHookSubscription2022 subscription type

[michielbdejong]

We've started experimenting with implementing webhooks. The notifications spec gives a pretty good description of how they should work, but doesn't specify an RDF class name for them.

To be able to add them as a second subscription type, next to WebSocketSubscription2021 we were thinking of calling it WebHookSubscription2022.

Is anybody else working on webhooks already and maybe already using a different class name to announce them? If so, let's coordinate! :)

It will also have to be added in solid/vocab#62 and in https://github.com/solid/specification/blob/main/notification-subscription-types.html

There is a client https://github.com/o-development/solid-webhook-client

I see that solid/vocab#62 only includes notify:WebSocketSubscription2021 I guess currents drafts of subscription type could be added there.

For reference, here are our WIP implementation in Solid-Nextcloud and WIP tests in the Solid CRUD tests

@michielbdejong is the major change you have around the content of the notification or around the notification method itself. If it's the former, I think that should be a part of the general notifications specification rather than something specific to to webhooks

[michielbdejong]

it's not a major change, note that the existing one is WebSocketSubscription2021 and the one that seems to be missing (unless we misunderstood) is WebHookSubscription2022.

The difference 2021/2022 is just that I thought the template was to add the current year at the time of proposing each one? Or should all subscription type names end in 2021?

Each subscription type spec should define IRI denoting it

https://github.com/solid/notifications/blob/main/webhook-subscription-2021.md#1-introduction

This document proposes an implementation for the WebHookSubscription2021 Solid Notification protocol.

I think the action here would be

• Updated draft to include full IRI in W3C namespace
• Update Add Solid Notification JSON-LD context vocab#62 to include it defined as a rdf:Class similar to

The difference 2021/2022 is just that I thought the template was to add the current year at the time of proposing each one? Or should all subscription type names end in 2021?

Implementations should just rely on the full IRI. How we name the spec is not an exact science, IMO for this draft, either 2021 or 2022 works as long as it is used in a consistent way throughout the draft.

The original proposal was created and migrated to its current repo back in 2021 solid/notifications#23
