Re: [soa-rm] My stab at an SOA-RM concept map

I do, ...

To start with ...

semantics is much like architecture: it is about concepts and the  
relationships between them. In our case, however, the semantics of a  
service is really about the expectations for the service: what do we  
need to know in order to effectively use the service and what will be  
the expected result of using the service.

This last aspect is pretty open ended of course: the service model  
for my son's piggy bank may be identical to the service model for my  
grown-up bank: but the expected result of a withdrawal is  
dramatically different.

So, I think, that data model, policies, processing model, are all  
aspects of the semantics of a service.

To be able to capture the expected results of using a service  
requires a deeper modeling of the context in which services are  
deployed. Speaking personally, I am in favor of such a modeling, but  
perhaps people may be a little surprised at what would be involved  
(hint: it brings in concepts such as institutional facts, norms,  
roles, authority, empowerment)
