ArchiMate Metamodel

The ArchiMate core language defines a structure of generic elements and their relationships, which can be specialized in different layers. These layers are defined within the ArchiMate language as follows:

1. The Business Layer depicts business services offered to customers, which are realized in the organization by business processes performed by business actors.
2. The Application Layer depicts application services that support the business, and the applications that realize them.
3. The Technology Layer depicts technology services such as processing, storage, and communication services needed to run the applications, and the computer and communication hardware and system software that realize those services. Physical elements are added for modeling physical equipment, materials, and distribution networks to this layer.
4. The physical elements build upon the Technology Layer and add elements for modeling physical facilities and equipment, distribution networks, and materials
5. The motivation aspect
6. The implementation and migration elements.
7. The strategy layer used to model the Enterprise Architecture at a strategic level.
