3.1.2 Interaction of Roles

Basic interactions for data exchange and data sharing in the International Data Spaces

The figure below gives an overview of the roles and the interactions taking place between them. As some of the roles (Certification Body and Evaluation Facilities) are not actively involved in the everyday operations of the International Data Spaces, they are omitted from the illustration. Also, the figure does not include Software Providers and Identity Providers, because of the necessary connection of those roles with all other roles. The Software Provider would be connected to all other roles with the relation provides software. Likewise, the Identity Provider would be connected to all other roles with the relation provides identity.

Roles and interactions in the International Data Spaces

Figure 3.1.2: Roles and interactions in the International Data Spaces

This shows only the basic interactions taking place between the different roles in the International Data Spaces. For data exchange, additional, more specific interactions are necessary. These interactions are described in the Process Layer section of the Reference Architecture Model.

The table below gives an overview of possible (mandatory are marked with X or optional marked with (X)) interactions taking place in the IDS.
