Just a stub at the moment...

We need to choose and define terms (many which currently overlap), pare down this list:

• Hook
  • http://en.wikipedia.org/wiki/Hooking (refer to the hook as the handler)
  • Some refer to the "trigger" side as the hook (ie: "this site has hooks")
  • Common alternatives for receiving side:
    • Callback
      • classic, functional inspired
    • Handler
      • generic, "handler script/URL"
      • combinable, "hook handler (?), event handler"
    • Listener
      • event-driven inspired "event listener"
    • Consumer
      • generic, some say "webhook consumer"
    • Observer
      • not terribly popular / academic (common implementation use callback or event terminology)
      • from Observer pattern
    • Postback
      • play on callback and POST, clever but not popular
    • Subscriber
      • Popular in PubSub/messaging paradigm
      • Seems to connote content/messages (over code and programming)
• Trigger
  • Inspired by DB triggers
  • Focuses on the invokation/calling end
  • Common alternatives for sending side:
    • Publisher
      • Popular in PubSub/messaging paradigm
      • Seems to connote content/messages (over code and programming)
    • Producer
      • Opposite of consumer
      • Combinable with events: "event producer"
• Event
  • The noun the "verbers" deal with
  • Common alternatives:
    • Message
    • Notification
    • Call (as in callback?)
    • Payload
• Registration
  • Process of registering your callback/hook
  • Common alternatives:
    • Subscription
      • Has connotations of PubSub and content
• Delivery
• Discovery
  • Process that leads to registration
  • Process may involve getting meta-data about hooks/events
• Fulfillment
  • Different from delivery? Is this an alternative?
