Use cases

• Register for package changes
• Register for all revisions
• Notified of a package change
• Notified of a revision
• Deregistration

Design

• Default port: 5672 (standard for AMQP)
• Exchange name: 'ckan'
• Exchange type: topic exchange (most flexible)
• Routing keys: (see below)

Routing detail

Routing key format: "OBJ_TYPE" (NB tags should be identified by their name, not ID)

Example routing keys

• 'package' - Package edited/created
• 'resource' - Resource edited/created
• 'revision' - Any change
• 'db.clean'
• 'db.rebuild'

Example queue bindings that clients may use:

• * - no filtering - client receives all notifications
• package - only changes to packages
• revision - all revisions
• db - all database operations

Versioning

Since message payloads will be tied into the REST Entities, it makes sense to join up with the REST versioning. This could be achieved by providing new exchanges called 'ckan-1.1' perhaps?
