Key
A Key represents the unique identifier of an object. Our Key scheme is inspired by file systems and Google App Engine key model. Keys are meant to be unique across a system. Keys are hierarchical, incorporating more and more specific namespaces. Thus keys can be deemed 'children' or 'ancestors' of other keys:
new Key('/Comedy')new Key('/Comedy/MontyPython')Also, every namespace can be parametrized to embed relevant object information. For example, the Keyname(most specific namespace) could include the object type:new Key('/Comedy/MontyPython/Actor:JohnCleese')new Key('/Comedy/MontyPython/Sketch:CheeseShop')new Key('/Comedy/MontyPython/Sketch:CheeseShop/Character:Mousebender')
