uSubscription spec/detail questions

[AnotherDaniel]

During implementation of up-subscription-rust and the subsequent (and ongoing) specification rewrite (#238), so far these questions came up:

• Is it expected that a uEntity can register more than one custom topic for receiving update notifications?
• Is it supposed to be possible to register remote uuris as custom notification topics?
• Should remote UUris be excluded from all listeners except subscribe and unsubscribe?
• Do we need update/change notifications when remote SubscriptionResponses come in? Like, changing a topic status from SUBSCRIBE_PENDING to PENDING - which would then apply to every subscriber-topic combination at that point in time, with the corresponding number of Update messages…
• Is SUBSCRIBE_PENDING a valid state to receive from a remote SubscriptionService as a response to a subscribe() call?

• Is it expected that a uEntity can register more than one custom topic for receiving update notifications?

No you can not set the topic, notifications come on a fixed topic (the source URI)

• Is it supposed to be possible to register remote uuris as custom notification topics?

Custom notification topics is not permitted

• Should remote UUris be excluded from all listeners except subscribe and unsubscribe?

I think I need more info to understand what you mean here.

• Do we need update/change notifications when remote SubscriptionResponses come in? Like, changing a topic status from SUBSCRIBE_PENDING to PENDING - which would then apply to every subscriber-topic combination at that point in time, with the corresponding number of Update messages…

Yes.

• Is SUBSCRIBE_PENDING a valid state to receive from a remote SubscriptionService as a response to a subscribe() call?

No.
