I'm building an app which replicates collections of data objects among
groups of contributors/subscribers.
I use XMPP for transport & store-forward, and I've built a simple
replication & revision system on top of PubSub.
I'm considering open sourcing this code and documenting the protocol.
(Source is javascript requiring Strophe.) Creating a separate package for
this would entail some work, so I'd like to gauge potential interest...
My replication & revision system does the following:
Establishes pubsub nodes for shared collections
Reliably transmits (reliable requires IQ Notifications):
- invitations to join a collection
- invitation acceptances
- collection copies to new members
- resignations from a collection
- revisions to a collection, containing:
a) list of revised objects
b) diffs for added/modified objects
format is app-specific; common diff types may be specified
Obviously, it's very lightweight -- 5 message types (so far). It's not
focused on real-time apps per se, but could be applied thereto.
Also, I'd love pointers to other forums where folks could be interested...
