This is the summary of D-AG004: Ensures platform independence.
 
The goal as stated 
" 
D-AG0004 
ensures platform independence of web services components in a way that does
not preclude any programming model nor assume any particular mode of
communication between the individual components 

" 

1. Goal statement stays as is.
2. Crtitical Success Factors
 
a. Focus on using platform independent development tools and languages.
b. Interfaces to web components must be properly defined and designed.
c. Focus on defining the architecture in terms of components and the
relationships between them.
    Components are defined in terms of interfaces, that defines their inputs
and outputs and also the form 
    and constraints on those inputs and outputs. The relationships between
components are described in terms 
    of messages and the protocols by means of which these messages are
transmitted among the interfaces 
    of the components that make up the architecture. 
 
3. Derived Requirements

a. Consistent definition of web components
b. Good definition of web component Interfaces their inputs/outpus and their
constraints.
c. Use XML based techniques for defining messages/protocols for invoking web
components.
 
I have tried to summarize the points in concise format. I need feedback if I
have not expressed the summary in a proper language and/or format. 

 
thanks
