Hi Mark,

Right, it does obscure it.

Sure, but I'd say that a queried subset is different than a view,
because the query is explicitly not asking for a representation of
the full state.

But no matter, there are certainly multiple valid ways of looking at
this.  I was just presenting one that I thought would appeal to most
Web services people with a preference for an OMA-like architecture,
since the Web really is a distributed object architecture.

"Serialized", like Java serialization; snapshot the current state of the
object to a byte stream.  AFAIK, the term came from Modula 3.  Python
uses "pickle" too.  I use "serialize" and "pickle" interchangably, to
try to speak to those who may have used one term but not the other.
