There's an intriguing post on the REST list from Jeff Bone on this
issue:
http://groups.yahoo.com/group/rest-discuss/message/823
"In the process of buying into the OO religion, we failed to learn an
important lesson: OO rarely works as a large-scale integration
methodology. Generic interfaces and generic composition frameworks have
always demonstrated better scalability, reusablility, simplicity,
economics, etc. than OO. Cases in point: UNIX, Plan 9, the Web, Linda.
Until we as an industry learn the lessons these examples pose, we're
doomed to fail over and over again, developing technologies that cannot
withstand the test of time and ubiquity: ONC and DCE RPC, CORBA, DCOM,
etc."
I'm not sure exactly what "Generic interfaces and generic composition
frameworks" refers to, but I'm thinking that this goes quite a bit
beyond REST vs RPC and into some fairly profound issues of software
architecture. Has the OO paradigm really hit the wall, at least as a
meta-model for widely distributed applications? If so, what's the
alternative?
I also note the convergence between Andy Gray announcing a new version
of Ruple a few posts back, and Jeff Bone mentioning the Web and Linda as
architectures that *do* scale. Ruple is essentially a melding of the
Web, Linda, and XML.... and as near as I can tell is consistent with
REST principles, using essentially PUT, GET, and TAKE (=GET+DELETE) as
its primitive operations. 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 ....
