Tutorial :What is meant by WS-*?


I have seen the abbreviation WS-*, but I have not been able to figure out what this means, and why is it important?


WS-* is shorthand for the the myriad of specifications that are used for web service messaging.

Some of the services are:

  • WS-Security
  • WS-SecureConversation
  • WS-Federation
  • WS-Authorization
  • WS-Policy
  • WS-Trust
  • WS-Privacy
  • WS-Test

There is a lot of information to digest, depending on what you need. Here's a list of the specifications on Wikipedia.


The Web Service stack. There are a bunch of specifications for Web Services, and there names are written WS-whatever, for example: WS-SecurityPolicy. The * is used as a wildcard to indicate that you are referring to the Web Services stack.


That's the name of a set of standards related to web services by the W3C.


They're important because web services, by their very nature, need standards to interoperate between platforms.


WS-* refers to all the web service standards, eg WS-Security, WS-Addressing etc.

Wikipedia has a list.
