Good day! I retract from this argument due to XEP-0462: PubSub Type Filtering. Link: https://xmpp.org/extensions/xep-0462.html Thank you Stephen for raising my attention to pubsub#type attribute. On Fri, 7 Jun 2024 18:18:11 +0000 Stephen Paul Weber <singpolyma@singpolyma.net> wrote:
There is no special use case other than a dedicated node ID.
The purpose is a a concensus node ID which should ease on interoperability betweeen systems.
Suppose project Betula (links directory system) adds intergration with XMPP PubSub, and choses "betula" as node ID.
Normally I would expect node id to either be random (such as a UUIDv4) or user selected. Along with a user selected title which is usually what a users will see when browsing.
