Fundamental WS-* Extensions
Now that we've established the primary service sub-layers of our service-oriented environment, it is a good time to consider additional means of extending the feature-set of SOA.
This chapter provides entry-level, syntactical overviews of the following five key WS-* extensions:
- WS-Addressing
- WS-ReliableMessaging
- WS-Policy Framework
- WS-MetadataExchange
- WS-Security Framework
We first introduced concepts relating to the features provided by these specifications in Chapter 7. We now round out that discussion with a series of language element descriptions that provides some technical insight into how these features are realized.
