[graap-wg] question regarding offer example (pp. 48-51)

[Heiko Ludwig]

Tiziana,

the idea of the service description terms was to enable the description of 
a service, potentially from different perspectives by using multiple 
service description terms. The service name should help the specifiers 
which term belongs to which service, not just a target to point guarantee 
terms to. Guarantee terms are a good means to define those aspects of a 
service whose compliance you want to monitor individually, not summararily 
as part of the service. In the given example, we may interpret that both 
parties are happy if the service is performed, without specifying detailed 
guarantees.

Whether this is realistic is another question. The examples are mainly to 
illustrate the syntax and cannot be analyzed too thoroughly for their 
semantic content. What I really mean is we are lacking a good primer ...

Hi all,
I have a question regarding the offer example appears in the appendix of 
the 
ws-agreement specification (latest version of the document).
In that example there's a service description term that refers to service 
name "ComputeJob2", but the service scope of the guarantees all point to 
"ComputeJob1". I don't see the need of having service names that never 
appear in at least one guarantee term scope. Could you explain the meaning 

of this?

Thank you in advance,
Tiziana
