Jerry,

As discussed in today’s NSI call a clearer naming scheme would be helpful for service definitions, the following is proposed (with thanks to Inder and Tomohiro):

Service Capabilities Definition (SDC) –  This is often referred to as the ‘service definition’, so from Jerry’s document: ‘The Service Definition (SD) is a machine readable textual document that identifies each attribute of the service and the range of values that attribute will allow’.  … and I think defines a default value?

Service Request Description (SRC) – this is a request for a specific instance of a service.  It is created by the Requester Agent when it assigns desired values to each of the attributes described in the SDC.  The SRC is sent from the RA to the PA in a Connection Request.

Service Instance Description (SID) – this is a description of an actual service instance, the attribute values reflect the values chosen and confirmed by the Provider Agent.

Would these terms help clarify your service definition document?
