1 INTRODUCTION
The document deals with the initial registration process which is the initial mandatory step for new Catena-X network participants.
1.1 AUDIENCE & SCOPE
This section is non-normative
This standard is relevant for the following roles:
- Core Service Provider
- Onboarding Service Provider
1.2 CONTEXT AND ARCHITECTURE FIT
This section is non-normative
In order to register participants, the Core Service Provider operates a registration service where a registering company can enter its details to initiate the registration process.
The interaction between Core Service Provider and Onboarding Service Provider is defined in this standard.
Figure 1 shows a high-level view of a section of Catena-X. It consists of the following building blocks:
-
Catena-X Core Services -- Basic services, like for example discovery services, used by all participants of Catena-X. The core services are standardized by the Catena-X consortium.
-
Participants environments -- A participant can offer and consume data. For this, he needs an Eclipse Dataspace Connector as well as corresponding prosumer applications. The applications are provided by Catena-X application providers.
-
The Gaia-X Digital Clearing House (GXDCH) consists of a notarization service and a compliance service and can be operated by another party. GXDCH is a Gaia-X component and must therefore comply with the corresponding Gaia-X standards. GXDCH on the one hand verifies the legitimacy of Catena-X participants and on the other hand it ensures the creation of Gaia-X compliant self-descriptions.

1.3 CONFORMANCE AND PROOF OF CONFORMITY
This section is non-normative
As well as sections marked as non-normative, all authoring guidelines, diagrams, examples, and notes in this specification are non-normative. Everything else in this specification is normative.
The key words MAY, MUST, MUST NOT, OPTIONAL, RECOMMENDED, REQUIRED, SHOULD and SHOULD NOT in this document document are to be interpreted as described in BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all capitals, as shown here.
All participants and their solutions will need to prove, that they are conform with the Catena-X standards. To validate that the standards are applied correctly, Catena-X employs Conformity Assessment Bodies (CABs).
The registration process described in this document serves as reference for future implementations. Core service providers and Onboarding Service Providers implementing their own registration solution MUST demonstrate compliance by:
- Providing documentation of the registration process implemented.
- Proofing that the registration process includes all the mandatory steps as defined in this standard.
- Proofing that the registration process implemented delivers the mandatory results as detailed in this standard.

2.3.3.6 Submit registration

2.3.4 Company Data Validation
Once the company data are collected, it must be validated to ensure accuracy and completeness. The following validation checks MUST be performed:
- Verify that all required fields are filled out
- Validate the format and accuracy of the unique identifier
- Validate proof of conformity of the registering company
- CSPs should implement robust validation mechanisms to ensure the integrity of the company data.
- In order to avoid duplicates, onboarding service providers / core service providers MUST check whether the company to be onboarded is already registered.
2.3.5 Business Partner Number Creation
After the company data is validated, a unique business partner number must be generated for the registered company (if not already existing). The business partner number serves as a unique identifier for the company within the dataspace. The generation of the BPN as well as the to-be-used algorithm is covered in the business partner number standard.
- Onboarding service providers / core service providers MUST ensure that a Business Partner Number (BPN) exists or is created and linked to the company being registered.
2.3.6 Wallet Tenant Creation
A wallet tenant needs to be created for the registered company. A wallet tenant allows the company to securely store and manage digital credentials and assets in their own separated tenant/instance. CSPs and OSPs should have a mechanism in place to create a wallet tenant associated with the registered company. The wallet tenant should be securely provisioned and accessible only to authorized individuals.
- Onboarding service providers / core service providers MUST ensure that a Managed Identity Wallet is created for the company to be onboarded. The BPN MUST be stored in the Managed Identity Wallet as a verifiable credential and serves as a unique ID.
2.3.7 Credential Storage
As part of the registration process, the company's credentials (e.g., digital certificates, authentication tokens) must be securely stored. These credentials are used for authentication and authorization purposes. CSPs should implement secure storage mechanisms to protect the company's credentials from unauthorized access or tampering.
2.3.8 Gaia-X

- Onboarding service providers / core service providers MUST ensure the creation of a Self-Description (SD) of the Legal Person as part of the application verification process. The SD MUST be stored in a central location and MUST be in line with the GAIA-X standards/guidelines.
2.3.9 Registration Approval and Dataspace Access
- Only when all checks have been successfully passed, the onboarding service providers / core service providers MUST provide access to the services. If one or several application validation steps have not been passed, the onboarding service providers / core service providers MUST reject the registration or defer it for revision.
- Onboarding service providers / core service providers MUST provide feedback (success/rejection/revision) to the to be registered company.
2.4 TECHNICAL INTEGRATION
Onboarding service providers / core service providers MUST provide onboarding companies with information on the step required to complete technical onboarding (connector registration, technical user creation, etc.).
Onboarding service providers / core service providers MAY support with the technical onboarding (integration of corporate identity provider, connector registration, technical user creation, etc.).
3. ONBOARDING SERVICE PROVIDER
An Onboarding Service Provider helps companies register at Catena-X for the first time. The motivation for this may be that an onboarding service provider wants to make it easier for its own customers to get onboarded to Catena-X, or to make the Catena-X onboarding process smoother in general. The to be onboarded company only interacts with the Onboarding Service Provider for registration.
This chapter describes how to enroll on Catena-X with the help of an Onboarding Service Provider.

The registration API is specified in CX - 0009 CATENA-X REGISTRATION API.
Who may register with Catena-X using an Onboarding Service Provider
