Relationships and Relationship Connectors in ArchiMate: A Comprehensive Overview


In the intricate realm of enterprise architecture, the ArchiMate language serves as a powerful tool for modeling and visualizing the structure and behavior of complex systems. Central to this modeling language are relationships and relationship connectors, fundamental components that define the connections between various architectural elements. Understanding the nuances of these relationships is crucial for creating accurate and meaningful architectural representations.

Classification of Relationships

The relationships in ArchiMate can be broadly classified into four categories: structural relationships, dependency relationships, dynamic relationships, and other relationships. This classification is illustrated in the Figure above, providing a comprehensive overview of the connections that can be established within an architectural model.

  1. Structural Relationships: Structural relationships are employed to model the static construction or composition of concepts. These connections can exist between elements of the same or different types. Notably, some relationships in this category are “overloaded,” implying that their meaning varies based on the types of elements they connect.
  2. Dependency Relationships: Dependency relationships articulate how elements are utilized to support other elements. This category captures the dependencies that underpin the architecture, showcasing how certain elements rely on others for their functionality or existence.
  3. Dynamic Relationships: Dynamic relationships come into play when modeling behavioral dependencies between elements. In the dynamic realm of enterprise architecture, these relationships illuminate how elements interact and depend on each other during various stages of system operation.
  4. Other Relationships: Relationships that don’t fit neatly into the above categories are grouped under “Other Relationships.” These connections might have unique characteristics that distinguish them from the more conventional structural, dependency, or dynamic relationships.

Summary of ArchiMate Relationships 

Here’s a concise summary of ArchiMate relationships based on the information provided:

Structural Relationships Notation Role Names
Composition Represents that an element consists of one or more other concepts. image


→ composed of

← composed in

Aggregation Represents that an element combines one or more other concepts. image


→ aggregates

← aggregated in

Assignment Represents the allocation of responsibility, performance of behavior, storage, or execution. image


→ assigned to

← has assigned

Realization Represents that an element plays a critical role in the creation, achievement, sustenance, or operation of a more abstract element. image


→ realizes

← realized by

Dependency Relationships Notation Role Names
Serving Represents that an element provides its functionality to another element. image


→ serves

← served by

Access Represents the ability of behavior and active structure elements to observe or act upon passive structure elements. image


→ accesses

← accessed by

Influence Represents that an element affects the implementation or achievement of some motivation element. fig26


→ influences

← influenced by

Association Represents an unspecified relationship, or one that is not represented by another ArchiMate relationship. image


associated with

→ associated to

← associated from

Key Constraints and Guidelines

For clarity and precision, ArchiMate imposes certain constraints and guidelines on the use of relationships and relationship connectors:

  • No Relationships Between Relationships: ArchiMate explicitly prohibits relationships between two relationships. This constraint ensures a clear hierarchy and prevents ambiguity in the architectural model.
  • Consistency in Relationship Connectors: When using relationship connectors, all connected relationships must be of the same type. This ensures a cohesive and logical structure within the architectural representation.
  • Valid Chains of Relationships: A chain of relationships connecting two elements, facilitated by relationship connectors, is valid only if a direct relationship of the same type between those two elements is also valid. This ensures a coherent and meaningful connection between elements.
  • Aggregation, Composition, and Association Constraints: Relationships connecting an element with a second relationship are limited to aggregation, composition, or association. Moreover, aggregation or composition is valid only from a composite element to the second relationship.
  • Explicit Naming for Clarity: It is considered good practice to explicitly name or label relationships to avoid ambiguity or misunderstanding. Clear nomenclature enhances the interpretability of architectural models.

Permitted Relationships and Derivation Rules

The metamodel figures in ArchiMate documentation might not explicitly show all possible relationships for the sake of readability. However, ArchiMate Manual (Section 5.7) introduces a set of derivation rules to derive indirect relationships between elements in a model. This ensures that even if not explicitly stated, relationships can be logically inferred based on the defined rules.


Relationships and relationship connectors in ArchiMate form the backbone of effective enterprise architecture modeling. Adhering to the classification, constraints, and guidelines ensures that architectural representations are not only accurate but also interpretable by stakeholders. As enterprises evolve, the ability to model and analyze relationships becomes increasingly crucial in maintaining a resilient and adaptive architectural framework. ArchiMate, with its robust set of relationship constructs, provides architects with the tools needed to navigate the complexities of modern systems and design architectures that stand the test of time.
