A technology framework is a collection of things. It can include one or more architectures, technologies, concepts, models, and even sub-frameworks. The framework established by Web services is comprised of all of these parts.
Specifically, this framework is characterized by:
Another recommended addition to this list is the WS-I Basic Profile (introduced in Chapter 4 and further explained in later chapters). It provides standards and best practices that govern the usage of WSDL, SOAP, and UDDI features. Therefore, much of what the Web services framework is comprised of can be standardized by the Basic Profile.
In its entirety this technology framework is conceptually in alignment with the principles of service-orientation. To further explore this synergy, the next three sections are intentionally labeled to mirror the three sub-sections from Chapter 3 in which we first defined the parts of primitive SOA (Figure 5.1).
