Who: Roles in the Catena-X ecosystem

The Catena-X ecosystem operates on the principle of multiple distinct roles, designed to create an appealing and functional data space (see Figure Role Overview and Relationships). Participants can take on one or more roles in any combination, and multiple participants can fulfill the same role except for the CSP-B role. The CSP-B role can only exist once in the data space due to complexity and technical reasons. Provider roles receive a label through a certification or qualification process to demonstrate that they are trusted partners (see Chapter How: Life Cycle Management).
