I had a little chance to look into this paper today. As I discussed already, I believe that wording about EC require serious revision: EC exist on its own and regardless agreement with the service consumer. EC is the policy environment (all technical infrastructure elements and constraints may be expressed as policies) where the service is tested and can run providing characteristics announced in the service description. If consume wants to interact with the service, the consumer has to agree with the EC. However, EC is not that agreement.

I just came up with this – EC == service invocation preconditions, define by service provider and agreed upon by service consumer in explicit agreement

 

Service provider must treat ES as a run-time environment rather than "additional constraints are necessary in order for the service consumer to invoke particular actions". 

Sorry, no idea what this means

 

Finally, I am against "service consumer to invoke particular actions" - consumer invokes Service, i.e. service functionality. What actions the service performs is not a business of the consumer. Moreover, different service interfaces of the same service may expose different operations that may not be taken as service's actions; these operations are provided for consumers.

I think the question here is again terminology. An action, as defined in one pager is a service method. So depending on the amount of methods the service exposes it can support one ar more actions. So when a consumer invokes a particular action it invokes a particular method. The point we can try to argue is whether service methods is just a bad example of OO thinking about something that has nothing in common with OO or this is really advantageous.

Attached is the one-pager we talked about at today’s conference call.  For those who didn’t attend, the minutes should be posted shortly.  The purpose of this is for us  to come to agreement on these concepts and their  relationship to each other before next week’s call.
