Understanding Web Services specifications, Part 7: WS-Business Process Execution Language
You have a pretty robust system of services, but what you really want is an
application that makes use of them to implement your business processes. Web
Services Business Process Execution Language (WS-BPEL) provides you with a standard
technology for composing and combining Web services so they will do what you want at

Understanding Web Services specifications, Part 6: WS-Interoperability
The goal of Web services is to enable communication between different
software and hardware systems. These systems typically differ in both their hardware
and software configurations. These differences have been overcome through the
definition of standard protocols, such as those employed in building Web services.
Occasionally, incompatibility issues arise even when using these standard protocols,
which can lead to interoperability problems. This tutorial, Part 6 of the "Understanding Web Services specifications"
series, explains the nature and origin of Web service interoperability problems. This tutorial also introduces you to
the WS-I Basic Profile, which is a set of guidelines Web services should adhere to
in order to achieve optimum interoperability.
