Events Member

[benfrancis]

Subscriptions may be created to properties and actions by a GET request on a property or action resource which is upgraded to a WebSocket connection such that data can be pushed from the server to the client when necessary.

There may be use cases where a client wants to subscribe to events other than changes in property resources or the creation of or changes to action resources.

For example, a Thing may have a "temperature" property which could be subscribed to whenever the temperature changes, but the Thing may also want to emit an event only when the temperature passes a certain threshold.

Should we add an "events" member to the Web Thing Description in addition to "properties" and "actions" for this type of use case? Is there a way for events be represented by resources in a RESTful way?

Follow-up work may be needed to link to each event type.
