Digital Twin KIT

Vision & Mission


The aim of the Digital Twin Kit is to trace parts and materials across the entire value chain to enable data driven use cases over all n-tier levels without compromising data sovereignty. This Kit enables data and app providers to deliver solutions for building data chains and to send quality notifications on all levels and industries.

To provide the Catena-X Automotive Network with a uniform infrastructure to enable data-level interoperability between Business Partners is the purpose of the Digital Twin Kit. Regardless of the data's provenance, the Kit sets the scene for a comprehensive landscape of distributed Digital Twins of assets (mostly parts) along the entire lifecycle of the supply chain.


The Digital Twin Kit bundles the necessary standards, APIs, interaction patterns and reference implementations on how to build a Digital Twin for an asset. By adopting established standards and integrating them, the Digital Twin Kit leverages the conceptual and implementation work of existing communities while contributing feedback and Open-Source-Contributions back to the public. A priority is the seamless integration with other Catena-X developments such as the Connector Kit.

Customer Journey

With the Digital Twin Kit, all roles mentioned in the Operating Model Whitepaper are given the necessary tooling to format their data and APIs in a standardized manner.

Business Value

Point-to-Point integration between Business Partners is challenging. On the one hand, all questions of sovereignty, authorization, authentication must be agreed upon and implemented. That is covered by the Connector Kit and the services it relies on. What this Kit adds is a set of technologies that reduce the integration efforts on the data level. Data Consumers can develop their applications against data formats that are standardized and reuse them independent of whom they will consume the data from. This reduces the necessary investment significantly and saves a network-participant from a strict link between the application and the data model. Consuming applications can be substituted seamlessly if they are developed against the relevant Catena-X standards - further lowering the bar of entry for new applications in the CX-Ecosystem.

Use Case

Status Quo / Today’s challenge

This Kit's aim is not to solve a dedicated business problem. It is an infrastructure component, critical for scalable data sharing and integration. It does however deliver a broad set of capabilities that the use cases can leverage.

  • Well-defined API structure extensible by domain models. Each use case will want to share different data and the API expands with the scope of the model.

  • A distributed infrastructure of central and decentral components integrating hand-in-hand with backend-systems southward and the network northward.

  • Extensive meta-model to create a virtual representation of asses across their entire lifecycle.


The Traceability Kit and the Data Chain Kit build on Digital Twins and leverage many of this Kit's content. The Data Chain Kit would be unimagineable without the pre-defined endpoint- and payload-definition that is the Digital Twin Kit. Likewise, coupling the chains' elements would be impossible without a unified hierarchical structure running with all participants.
