The A3 Architecture Correspondence view identifies the relationships between architectural elements.
ISO42010 introduces the idea of architecture correspondence and correspondence rules. Quoting from ISO/IEC42010; “A correspondence defines a relation between AD elements. Correspondences are used to express architecture relations of interest within an architecture description (or between architecture descriptions). Correspondences can be governed by correspondence rules. Correspondence rules are used to enforce relations within an architecture description (or between architecture descriptions).”
NAF has a number of relationships, used throughout the framework. Rather than identify each relationship here, those relationships are shown in each meta-model excerpt for each view. Each view shows “Key Elements and Their Relationships” and “Meta-Model Excerpt“. In the meta-model excerpt, relationships are depicted as boxes with thin borders.
