  • data consumer, that are searching for detailed product informations in Catena-X and
  • Application developer/provider supporting the consuming data for detialed infromations of product in the markertplace of battery passports.

In the first version the Marketplace just consume data for offered Batteries. Therefore the application use the BatteryPassport data model.

1. INTRODUCTION​

This document defines the so-called standardization triangle for the Secondary Marketplace use case. Standardization triangle hereby means the mandatory components, data models, APIs etc. that are required to enable the Marketplace use case. Additionally, search objects as well as procedures to registering/providing and consuming the data will be defined.

1.1 AUDIENCE & SCOPE​

This document is meant for the following roles:

  • Data Provider / Consumer
  • Business Application Provider

1.2 CONTEXT​

For release 3.2, the secondary marketplace will be displaying additional information on the products, specifically batteries. In order to offer additional information about the battery to potential buyers, the marketplace uses the BatteryPass sub-model. This allows buyers to access real data (detailed content see CX-00034)

1.3 ARCHITECTURE OVERVIEW​

  • Eclipse Data Space Connector (EDC) or equivalent components in compliance with the standard CX-0018.
  • Usage of the Discovery Finder to find relevant BPN Discovery Endpoint(s) following the Catena-X Standard CX-0002.
  • Usage of the BPN Discovery Services to find relevant BPN-L(s) following the Catena-X Standard CX-0002.
  • To find relevant EDC Endpoints the BPN Discovery Service is used following the CX-Standard CX-0001.
  • Usage of dencentralized digital twin registry to provide twins of products following the the CX-Standard CX-0002.
  • To find relevant EDC Endpoints the BPN Discovery Service is used following the CX-Standard CX-0001.
  • connections to components for authenticate as a data provider or consumer following the onboarding Standard CX-0006 and the identity and access management standards (CX-0013-0017)

1.4 CONFORMANCE​

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).

To prove conformity with the use case marketplace standard standard as a data consumer or app provider demonstrate that you

  • can find battery twins
  • can distinguish the battery passport information from other submodels
  • can visualize battery passports.

To prove conformity with the use case Marketplace standard as data provider you MUST show that you follow the standards listed under 2.1 List of Standalone Standards

To prove conformity with the use case Marketplace standard as app provider you MUST show that you follow the standards listed under 2.1 List of Standalone Standards

1.6 EXAMPLES​

No Example provided.

1.7 TERMINOLOGY​

The following terms are especially relevant for the understanding of the standard:

  • Asset Administration Shell (AAS): The AAS is chosen standard in Catena-X to define Digital Twins of an asset (e.g. a battery or a full vehicle).
  • Business Partner Number (BPN): A BPN is the unique identifier of a partner within Catena-x.

Additional terminology used in this standard can be looked up in the glossary on the association homepage.
