RE:  MS thinks HTTP Needs Replacing???
This is precisely what the Unisys managers told 
us during the MID project.  It interested them 
precisely because we turned our backs on passing 
complex objects and passed only data objects.  If you have 
to scale outwards, you have to reduce vertical 
complexity (depth).  It comes down to why 
the mail sends you letters in envelopes (only 
handle the address information and size issues), 
why children are taught to read with phonetics, 
and composers are best taught harmony at a gross 
level over counterpoint first.

This may be news to the web, but hardly anywhere 
else.  OOP was meant to solve programmer problems: 
maintenance and reuse.  Relational solves problems 
for the data owner:  maintenance and reuse.  Hypermedia 
solves a problem of creating relationships among 
data that has different owners but does not necessarily
help maintenance and reuse.  It's easy to design 
hypermedia systems that fail at that and harder to 
design ones that don't.   Putting controls in 
the text is one part of the problem.  Systems 
that point in are easier but only if the change 
control is absolute.   

At the end of it all, hybrids are the solution, 
so no, this is not the beginning of a new meta 
model for large scale architecture.  Not at all. 
It's the same stuff with hypermedia being brought 
forward as mainstream rather than lunatic left 
wing fringe.

Are we seeing the outlines of a new meta-
model for large scale software architecture that challenges a lot of the 
received wisdom of the OO paradigm? 

That is, perhaps "encapsulation" of data is not such a good thing after 
all ... or at least it's not scaling well to the Web. Perhaps it makes 
more sense to expose the data via generic operations rather than 
exchange objects that encapsulate data behind customized operations. I'm 
not sure, but things are getting interesting ....
