scope:

The present document is part 9 of the Stage 3 specification for an Application Programming Interface (API) for Open Service Access (OSA).

The OSA specifications define an architecture that enables application developers to make use of network functionality through an open standardised interface, i.e. the OSA APIs.

The present document specifies the Generic Messaging Service Capability Feature (SCF) aspects of the interface. All aspects of the Generic Messaging SCF are defined here, these being:

Sequence Diagrams

Class Diagrams

Interface specification plus detailed method descriptions

State Transition diagrams

Data Definitions

IDL Description of the interfaces

The process by which this task is accomplished is through the use of object modelling techniques described by the Unified Modelling Language (UML).
