A cute and surprisingly well-behaved discussion about my recent post on the plumbing wars.

As he
yesterday, Clemens describes his RESTful extensions to WCF/Indigo
in a most enjoyable
article on his weblog.

I really liked his detailed comparison of the HTTP and SOAP (as-practiced)
dispatching models, as well as that of RPC vs. uniform operations. While there were a
few little things I disagreed with, they weren’t significant enough to warrant
mention, so I won’t.

Unfortunately, I’m not a big fan of his extensions.

I think the mapping he lays out there is reasonable in cases where
you’ve already got legacy code with legacy interfaces which
need binding to the Web, because you can just annotate those existing
interfaces with these extensions. But when you’re developing new code,
what purpose do service-specific interfaces serve? Nobody’s invoking
them, since they’re just invoking the HTTP methods. So why are they there?
I think that can only serve to hide the resource-centric REST model away
from developers, and make other tasks more difficult; for example, dealing
with resource collections.

I think the general approach to Web based models should resemble
HTTP Servlets.
Not to suggest that Java, nor inheritance, nor any language-specific feature
of Servlets themselves need be used. But instead, just to say
that the logical model of a RESTful programming framework should be one
which requires “objects” (or “services”, or whatever you want to call them)
expose the uniform interface.

FWIW, the best (for my definition of “best” 8-) one I’ve seen so far –
though I haven’t vetted it yet – is this
nameless Ruby one
which is, AIUI, proposed for use as a
Rails extension.

“The traditional distributed computing guys, like myself, have difficulty adjusting to the difference that XML makes”. Amen to that.
