Primary concepts In the technical layer, the three specializations of the building blocks can be relatively easily related to an ArchiMate element, namely:

• Service <-> Technology_Service
• ABB <-> Technology_Function, as already mentioned, another behavioral element can also be used here
• SBB <-> System_Software, Node, Network, Device, Path and other technical active structure elements.

ArchiMate relationships can be defined between the elements:

• Service <-> ABB: Realization
• SBB <-> ABB: Assignment
• xBB <-> xBB: Aggregation

The last association, aggregation, is particularly important because it allows composite building blocks to be put together. In addition to the associations mentioned, several types of associations can be selected, such as dynamic associations. When developing the views within this viewpoint, you are free to apply these additional associations, provided they are elaborated in the general viewpoints already present. Secondary concepts In addition to the primary elements and associations, elements and associations are relevant, but not in all architectural domains. These are:

• Technology_Interface, also within the integration architecture, for the implementation of, for example, a web service, this concept is necessary as an additional ArchiMate element within the xBB modeling.

An introduction of an artefact is only relevant in certain sub-areas (geo). In other cases, a language with more detail will be used, such as UML class diagrams or XSD models. In the latter case, an association is made between the modeling language concepts via a trace.
