Understanding the ArchiMate 3.2 Metamodel: A Guide to Behavior and Structure Elements

Introduction

The ArchiMate language serves as a powerful tool for enterprise architecture, allowing practitioners to model and visualize complex systems and their interrelationships. At the heart of ArchiMate lies its metamodel, a fundamental structure defining the elements and relationships that constitute the language. In this article, we delve into the generic metamodel of ArchiMate 3.2, focusing on the hierarchy of behavior and structure elements.

Overview of the Generic Metamodel

The generic metamodel provides a foundational structure for the ArchiMate language, offering a layer-independent representation of its key elements. It’s crucial to note that the relationships depicted in the metamodel figures are not the same as the relationships within ArchiMate models. Instead, these relationships express the structure of the language itself, guiding how elements are organized and related at a conceptual level.

Behavior and Structure Elements

The main metamodel fragment, presented in the Figure below, outlines the hierarchy of behavior and structure elements in ArchiMate. These elements are categorized into two main types: structure elements (referred to as “nouns”) and behavior elements (referred to as “verbs”).

Structure Elements:

• Active Structure Elements: These are further divided into external active structure elements (interfaces) and internal active structure elements.
• Passive Structure Elements: These elements play a more receptive role in the system.

Behavior Elements:

• Internal Behavior Elements: Representing behaviors intrinsic to the system.
• External Behavior Elements (Services): These are services provided by the system.
• Events: Signifying occurrences or happenings within the system.

Relationships in the Metamodel

The Figure below illustrates the main relationships between behavior and structure elements in the ArchiMate metamodel. It’s important to understand that this figure serves as a generic template, not exhaustive in representing all permitted relationships. The label of a relationship signifies the role of the source element in that relationship. For instance, a service serves an internal behavior element.

Key Considerations and Clarifications

1. Abstract Metamodel Elements: Most of the elements depicted in the metamodel are abstract. They don’t get instantiated in actual models but play a crucial role in structuring the metamodel.
2. Layer Independence: While the generic metamodel provides a foundational structure, each layer in ArchiMate defines its specialized version of this metamodel. This layer independence allows for flexibility and adaptability in modeling diverse architectural perspectives.
3. Relationships and Specializations: Beyond the relationships highlighted in the figures, every element in the language can have composition, aggregation, and specialization relationships to elements of the same type. Additionally, there are indirect relationships explained in detail in Appendix B.

Conclusion

The ArchiMate 3.2 metamodel, with its emphasis on behavior and structure elements, serves as the backbone of the language, offering a systematic and layered approach to enterprise architecture modeling. Understanding this metamodel is essential for practitioners seeking to leverage ArchiMate effectively, providing a solid foundation for creating comprehensive and insightful architectural models tailored to specific organizational needs.
