S3 — Service Interfaces

Purpose & Usage

The S3 Viewpoint is concerned with the identification and specification of Service Interfaces.

• Service implementation guidance.
• Service interoperability.
• Service integration.
• Defining Service interfaces and their boundaries.

Scope

• Shall contains Service Interfaces specified by a Service.
• May show Service Operations for Service Interfaces.
• May show Service Operation Parameters for Service Operations.
• May trace Service Operation Parameters to Physical Passive Resources.

Representation

• Tabular.
• Diagram.

Notes on the Cut-out

The link between a Service Operation Parameter and a Data Model is realized transitively through a Physical Passive Resource.
