What: Service Map
The architecture of the Catena-X Operating System (cxOS) is derived from the reference architectures of the International Data Spaces Association (IDSAIDSA The IDSA is an organization working to create the future of the global digital economy with International Data Spaces (IDS): a secure, sovereign system of data sharing where participants can realize the full value of their data.) and Gaia-X. The cxOS consists of three areas: Core, Onboarding, and Enablement Services shown in Figure Service Map.

Service Map (Deployment View)
The operating system (cxOS) is the technical foundation, enabling business use cases to operate in a network-enabled manner across company boundaries. The cxOS offers various capabilities:
Enablement Services
The Enablement Services are a bundle of decentral services that enable participation in the Catena-X data space. Each participant must deploy and use the enablement services to connect to the data space and enable standardized interactions, based on the requirements of the respective use case. They ensure the strategic value proposition of technical/semantic interoperability and (data) sovereignty.
The connector (e.g., EDC), based on the Data Space Protocol, and the identity wallet, form the mandatory basis of enablement services enabling standardized technical connectivity and sovereign data exchange. All participants can use them to establish a basic connection to the data space, independent of the business use case.
In addition to generic data exchange capabilities, enabling services include context-specific service offerings. Examples are the Asset Administration ShellAsset Administration Shell The AAS is a digital representation of an asset; it is a form of a digital twin. (AAS) as a harmonized access layer for digital twins, the Decentral Digital Twin Registry (DDTR) for local discoverability of digital twins in decentral organized data spaces or the Item Relationship Service (IRS) for building data chains and iterating through a tree structure of digital twins.
Please note that there are various options for running enablement services, ranging from leveraging software-as-a-service solutions to local deployments of open-source reference implementations. Further information on deployment and usage premises can be found in Chapter EDC Deployment and Usage Premises.
Core Services
In contrast to Enablement Services, Core Services are provided and operated by Core Service providers A/B. Core services provide common accessibility and discoverability functionalities for data space participants. Examples include BPNBPN A BPN is the unique identifier of a partner within Catena-X. issuer for maintaining business partner numbers, and participant information, IAM solutions for identity and access management, and discovery services to localize the address of assetsAsset On the Data Provider side, an Asset describes the data set which will be shared or can be consumed by a Data Consumer. in decentral organized registries across the data space. The Core Services can be divided into two areas:
Core Services A lists Core Services that can be operated “n” times in the Catena-X data space.
Core Services B lists Core Services that can only be operated once in the Catena-X data space due to business reasons or technical limitations and are therefore tendered via the nomination process of the Association.
