Its funny but so few people who also use ESB and WS-* style protocols and tools frequently operate with such disdain for other ways of doing things.
There are, of course, a very large number of automated solutions to a particular problem. But of all of them, only a few will exhibit the desired properties, to the proper degree, that you require for the environment in which it is to be deployed. The more you require, the fewer the number of suitable solutions.
To say, as Sam and Tim both do, that REST is important is like saying the fan in my laptop is “important”. There’s really nothing to discuss about it. RESTful services are fundamentally critical to the continued evolution of the Web. It just is. You just need to do things in a RESTful way. Period.
REST is just a starting point. What’s more important going forward is the framework which permits us to reason about REST extensions and other changes to the Web (or portions thereof).
So, while the two Marks are suggesting Pat’s reached REST the hard way, I would suggest this is something he’s been saying for years, […]
That is the hard way! 8-O If Pat’s been unknowingly preaching REST constraints for years, then he’s done it from scratch. That’s a great personal accomplishment of course; I wish I were that smart. But wouldn’t it have been great if he had noticed that what he was talking about was being built out right under his nose for the past 15 years? 8-) I don’t fault him for that any more than I fault the bulk of the industry for also missing it (which is to say, a tiny bit 8-).
Anyhow, hopefully this paper can be the catalyst that helps push the industry towards a better understanding of the power and value of the Web. Of course, it also brings a new perspective to bear on the Web itself, from a seasoned distributed computing veteran, so that can only help Web proponents, perhaps motivating new Web based solutions. At the very least, they’ve got me thinking, which is always good 8-)
… is the title of a new blog post by yours truly on my consultancy’s weblog.
Paul writes that innovation in the browser ain’t dead yet. I agree. From a distributed systems POV, I think there’s two important things that need to happen to the browser, in addition to the richer languages that Paul talks about (and don’t forget about RDF and OWL!);
- making the browser a peer
- allowing the browser to own application state
The latter, related to the former, suggests that cookies can be replaced by purely client-side application state. What this would look like, is that you’d drag-and-drop items from a browser window into a desktop-located container – for example, a shopping basket – and then to check out, you drag the container back to the page. This keeps the session state – the basket – on the client, per REST’s Stateless constraint. This would require an extension to HTML/XHTML to support draggable objects, as well as a means to support file upload via a drop action (i.e. targetted at some element on the page).
