3.1 Business Layer

The Business Layer of the Reference Architecture Model defines and categorizes the different roles the participants in the International Data Spaces may assume. Furthermore, it specifies basic patterns of interaction taking place between these roles. It thereby contributes to the development of innovative business models and digital, data-driven services to be used by the participants in the International Data Spaces.
While the Business Layer provides an abstract description of the roles in the International Data Spaces, it can be considered a blueprint for the other, more technical layers. The Business Layer can therefore be used to verify the technical architecture of the International Data Spaces. In this sense, the Business Layer specifies the requirements to be addressed by the Functional Layer.
