What is the difference between composition and aggregation in ArchiMate?

Composition represents a strong whole-part relationship where parts cannot exist independently of the whole, whereas aggregation is a weaker whole-part link where parts can belong to multiple aggregations.

How does this skill help with cross-layer ArchiMate mapping?

The skill provides validated patterns for connecting layers, such as using 'serving' relationships between Application Services and Business Processes, or 'realization' between Artifacts and Data Objects.

Does this skill provide notation examples for data access?

Yes, it includes specific notation for the Access relationship, including mode indicators like (r) for read, (w) for write, and (rw) for read-write access between functions and data objects.

What direction should relationships point in ArchiMate modeling?

ArchiMate relationships generally point toward enterprise goals. The canonical flow moves from Technology to Application to Business, and from Active Structure to Behavior to Passive Structure.

Design Tools

Guides the selection and implementation of ArchiMate relationships for accurate enterprise architecture modeling and cross-layer alignment.

The ArchiMate Relationships skill provides specialized guidance for architects and developers using Claude Code to build logically sound enterprise models. It categorizes the 11 core ArchiMate relationship types into structural, dependency, dynamic, and other classifications, ensuring every connection in your architecture follows formal standards. By applying directional principles—moving from Technology to Business and from Active Structure to Passive Structure—the skill helps users maintain model integrity. Whether you are mapping application services to business processes or defining data access modes, this skill provides the patterns and notation rules necessary for high-quality architectural documentation.
