question regarding offer example (pp. 48-51)
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 ******************************************** Tiziana Ferrari Tiziana.Ferrari@cnaf.infn.it Italian National Inst. for Nuclear Physics / CNAF v.le Berti Pichat 6/2, 40127 BOLOGNA, ITALY tel: +39.051.6092.759 fax:+39.051.6092.746 http://www.cnaf.infn.it/~ferrari ********************************************
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 ...
