This is just a quick thought that came to me whilst making coffee this morning...

REST places focus on nouns (resources) in a system. Whereas it seems web services are more concerned with verbs. A service is a collection of operations. The data is passed to and from operations as messages.

Now both approaches have their merits. What strikes me as strange is our choice of programming languages when attempting to implement the aforementioned architectural styles. Object orientated programming is all about nouns (classes). Functional programming is all about verbs (functions).

I know that there is way more to web services than just a bunch of operations (because that would be simply RPC right?). However, my point is that surely OOP is ideally suited to describing a set of resources as required by a RESTful design.

I am yet to play with the new ASP.NET MVC framework. However, I am spending time reading around the area to see if it will benefit me to get more involved.

A concern that came to mind when researching is the claims of it enabling a RESTful approach to web programming. Whilst this may be true, all the examples so far seem contrary to REST. My limited understanding of REST says that URLs represent a Resource. How is http://www.mysite.com/customers/delete/42 a resource?!

Yet that is indeed the format of URL we are being shown by Scott Guthrie and others. It makes ASP.NET MVC look more like another RPC system, just with parameters encoded into the address instead of message body.

So is it possible to specify a resource URL and then a number of HTTP verbs that can execute against it? It probably is, given the extensibility of ASP.NET MVC's architecture. However, one may ask, should I be hacking this into the framework? Would the end result look anything like the original MVC code at all? Probably not!

Is it time for a real REST framework built on top of ASP.NET? I think it is!

It needs to be Resource centered. It needs to fully leverage the rich feature set of HTTP, not just GET and POST! And just to be awesome, it needs to have a client-side story too. Real REST relies on the client-side to store state. Could this be Silverlight, or do we still want JavaScript? (I'm up for cross compiling to JS from C# or MSIL!)
