What Are The Drawbacks Of REST?

What Is Idempotent in REST?
What Is Idempotent in REST? One of the important aspects of REST (or at least HTTP) is the concept that some operations (verbs) are idempotent. Idempotency is also discussed in the SOA Design Patterns. For instance, does it matter if an operation only appears to be idempotent to users, when in fact it does change some state, such as updating a logger?

Has Web Style Worked?
Almost 7 years ago Tim Bray declared SOA dead and the future was Web Style. In a recent blog post Jean-Jacques Dubray looks back over the years and decides that Web Style hasn't worked and, given the plethora of non-Web Style services in the Programmable Web directory, is in fact itself dead.

Architectural Homeopathy
In a recent article Steve Jones discussions a group of people he calls Architectural Homeopaths, who make critical architectural decisions based on "powerpoints and opinions" but with a lack of clear evidence to support them. He says they are prevalent in IT and believes that those people who push REST for enterprise integration fall into this category.

Getting Started with OData v3 and WCF Data Services 5.x
If you are building new web services with .NET then OData should be high on your list of frameworks to investigate, especially if you need to support unknown third parties. The technology inherently supports both SOAP and REST style messages with the latter offering ATOM (XML) and JSON representations. This means consumers can pretty much request whatever format is best for them.

Shoehorning Java into RESTful Design
In a recent Zapthink article the author discusses why Java and JAX-RS 2.0 are not always appropriate for building RESTful services. Much has been said about the improvements in JAX-RS 2.0 but it is the Java object model which the author believes is at the heart of at least one of the problems, with REST being shoehorned into Java or vice versa.

Is It Time For WADL in JAX-RS?
At JavaOne 2012 in a panel session around the future of Java EE, the audience were keen to know whether or not WADL should be a standard part of JAX-RS. Although the panel were unable to agree, the audience appeared to be more pro WADL than against. So is this a good thing or is WADL still considered unnecessary for successful REST?
