(defprotocol IObservableCollection
  "Defines the minimum protocol required for an observable collection
  to be bound to an items-view."
  (-subscribe [coll key f]
    "Where f is a functional taking 3 arguments:
      the key, the collection, a sequence of changes in the form of:
        [[key1 new-value1]
         [key2 new-value2]
         [key3] ;; missing new value indicates the element was removed
         ]
    When the subscription is first initiated the collection will call f
    some number of times passing the existing data in the collection.
    If a collection would like, it may add additional information to the change
    set using metadata.")
