[Standards] Re: Bibliography and PubSub

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.
