The section explores
the expressive power of the Identity Metasystem and its soundness,
describing how its various parts can be composed for handling
different example scenarios in ways that are fully
respectful of the identity laws.
The section ???WS-* Web Services Speci?¬?cations: The Rei?¬?cation
of the Identity Metasystem??? provides a brief overview of the
advanced web services speci?¬?cations, positioning the trend in
the industry landscape and delving into the details of some especially
relevant speci?¬?cations. After all the pertinent details
have been spelled out, the text shows how the abstract
constructs in the Identity Metasystem ?¬?nd a concrete counterpart
in the web services world. A sustainable solution for the
online identi?¬?cation system has ?¬?nally been found, and the
technological means to put it into practice are already mainstream.
The section ???Presenting Windows CardSpace??? positions
Windows CardSpace in the Identity Metasystem, explaining its
role and its relationship to the other components of the solution.
By the end of this chapter, you will understand the Identity
Metasystem, how it works, why it is the way it is, why it can
aspire to be a global solution, and why former attempts fell
short.
