Questions related to Web-Services [RESTfull, RESTless, WSDL, Security]

Thats the first time i gonna digg into webservices. Right now i am going through articles for RESTFull webservices, found from the stackoverflow dis开发者_Python百科cussions. Going through articles, i have few questions.

• What is the difference between RESTFull and RESTless
• What is WS-*? is it also a webservice standard? what is the difference between RESTFull and it?
• I got very basic knowledge of RESTfull services. I am wondering, how security is implemented in it?

I know most of you guys will say and recommend me to read these from different articles. which i will but for time being these questions are stuck in my head. I am not looking for some details or referred to other articles type answers. Just one liner or very basic difference.

Thanks,

To my knowledge there is no common understanding of the term "restless".

In my opinion a REST based system is RESTful. Some people have decided that RESTful is a watered down version of REST.

WS-* is a set of standards implemented on top of the SOAP protocol and is alternative to building a REST based architecture. Going into the differences is a large topic. In summary, WS-* is based on using RPC for distribution of functionality, REST takes a different approach described in Roy Fielding's dissertation.

If you are doing REST over HTTP then you should use whatever security mechanisms HTTP provides. e.g. Basic, Digest, SSL, OAuth, etc.
