A3 — Architecture Correspondence

Purpose & Usage

The A3 Viewpoint is concerned with implementing correspondence between elements of Architecture Descriptions (AD).

• Traceability / dependencies between architectures.
• Re -Use of Architectures.
• Dependency analysis across architectures.

Scope

• Shall contain all relevant Architecture Description Elements.
• Shall contain Element Correspondences that relate to Architecture Description Elements and Correspondence Methods that govern them.
• May show how Architecture Descriptions relate to Architecture Description Elements.
• May show how Architecture Descriptions relate to Element Correspondences.

Representation

• Tabular.
• Diagram.

Notes on the Cut-out

The concepts of architecture correspondence presented here are derived from ISO/IEC/IEEE 42010. An Architecture Description element can have any level of granularity, ranging from a component of a view to a complete architecture description.
