Jupiter

Jupiter is a test bed for ActiveResource over XMPP using Switchboard and a modified version of ARes in the activeresource-xmpp branch of mojodna/rails (forked from Rails 2.2.2).

See test.rb for sample usage. (It uses app/models/post.rb as the resource descriptor.)

ActiveResource is extremely tied to HTTP (e.g. use of Content-Length headers and HTTP verbs), but there's no reason that it shouldn't work over a separate transport that can handle REST semantics. XMPP's use of asynchronous _retract_s and _publish_es cause particular problems, as ARes expects responses immediately. XmppConnection could be adapted to block on those operations, but that potentially eliminates some of its power.

XMPP also provides the ability to subscribe to event notifications when items are published, updated, or retracted. Hooks could be built into ARes models so that applications can listen and respond to such notifications.

Getting Started
