Interface unique name in the form of hostname component, which is the Interface short name, prepended to the SE unique name per Int - Interface unique name: uri The interface unique name is tightly coupled to a specific service enabler name and is to be unique across all SEs. The i

12、nterface is a defined subset of functions of the service enabler - i.e. a service enabler could have multiple interfaces. NOTE: Interfaces and Service Enablers are both considered services in the TM Forum Information Framework (formerly known as the SID model). The distinction is made here to highli

13、ght the relationship between the interfaces and their function as an aggregate service. In reality, they are each SID services that are essentially useless if delivered separately. 7.

30、fering the SE to the user 25. Terms and conditions to which the Consumer must agree constraints under which the SE provider allows the SE to be consumed (e.g., might include transaction volume limitations, extent of liability if the SE isnt working right or the SE is turned down, whether the SE prov

32、aracterization overlap with and are related to identity management. Item 15, SE consumer interface security policy, addresses the nature of the users identity and credentials supplied to the SE when consuming the SE. Item 16, User profile dependencies/relationships, identifies profile information re

33、lated to the user identity. Item 22, Identity of the entity that created the SE, may be informational, but this information could also be part of a service catalog where the creating entity is formally related to the service enabler and must authorize use of the enabler. The intent of this document

34、is not to define a separate identity management structure. This document simply specifies the connections between the service enabler and the identities that create and use that service enabler.
