It would be irresponsible for me to say this without also referring
you to Dan Connolly's extremely non-vague formalism for the Web:


However, I believe this model needs some refinement. For instance
-- somewhat surprisingly -- it does not define any concept of
linking, only of objects ("entities") and object addresses ("URIs").

Also, the only stateful (time-dependent) part of this model is the
"representation" of URIs by entities, and even that is strictly
under the control of timed expiration. Thus, the entities
themselves are specifically _not_ stateful (probably a good choice).
