Just a small summary / follow-up from todays xsf@ discussion. * Georg Lukas <ge...@op-co.de> [2017-07-13 21:56]: > Maybe OTR and MUC-PMs are the only pathological cases here. Then you are > right and we don't even need <no-copy/> / <private>.
Daniel's point that OTR and MUC-PMs are a legacy exception and that the default rule should be "messages get delivered to all resources, IQs go to a specific resource". That makes sense for me, so I'm convinced we should remove <no-copy/> from Hints and leave <private/> in Carbons for compat reasons. Regarding message storage (offline, MAM, MA or anything else) and the related issue of which messages to forward immediately through CSI / when to trigger Push: The relevant semantic information we want to encode is: - "transient" message: this message doesn't change permanent state and is only informational; examples are Chat State Notifications, Real-Time-Text. There is no need to archive those, and they can safely be skipped from a CSI-inactive stream. In theory, this is similar to type=headline, but that won't work well with MUCs and might have other issues. - "persistent" message: this message should be delivered to the receiver, stored offline / archived etc. This can be the default for all messages, so absense of a "transient" hint automatically means "persistent". This would also include 0184 ACKs, read markers and other bodyless messages. We have no consensus yet on how to handle "push urgency" - not every message that is "persistent" also requires immediate delivery to the client. With the above points considered, Hints would be reduced to a single "no-archive" or "transient" hint, making it a rather thin XEP. Still, I think it is useful to have it in a separate place from MAM, because it provides the semantic information for CSI and Push as well. Now the questions for the council would be: - Do we want to rename "no-store" into "transient" to make the semantics clear? - Do we want to revive "Hints" as a "Hint" XEP? Is there a better place for "transient"? - Do we want to add more hints related to push? Georg -- || http://op-co.de ++ GCS d--(++) s: a C+++ UL+++ !P L+++ !E W+++ N ++ || gpg: 0x962FD2DE || o?
