This guide provides a comprehensive overview for setting up a Digital Twin Registry (DTR) in Dataspace OS.
What is a Digital Twin Registry?
A Digital Twin Registry in Catena-X is a centralized system that maintains digital representations (or "digital twins") of physical assets, enabling businesses in the automotive supply chain to share, monitor, and update asset data securely and efficiently. It leverages submodels (Catena-X Submodel Services) to organize and manage specific aspects or attributes of assets, such as manufacturing data, lifecycle information, or quality metrics, allowing for modular and detailed insights.
The provider publicizes digital representations (digital twins) of the assets the participant has data on. This data is encapsulated in submodels accessible via instructions that a consumer will find in the Digital Twin Registry (DTR). The DTR contains only meta-data.
Asset Identification and Tracking - Registers and identifies assets to provide a comprehensive, trackable digital representation across their lifecycle.
Data Standardization and Interoperability - Ensures data consistency and compatibility by using standardized submodels for seamless data sharing among partners.
Real-time Data Access and Updating - Allows for live updates and real-time access to asset data, ensuring up-to-date information is always available to authorized stakeholders.

Required Participation
To add a DTR, make sure you participate with Catena-X Dataspace (see Add a Dataspace).
Step 1 - Components View
From the menu select Components.
This view allows you to search, add, edit, and remove components, while displaying details such as component type, version, name and state. This view also contains the Audit which logs all components.
Search and Filter
Use the Search field 🔎︎ in the top left to look up a specific component. The list will only show components which contain the entered name.
Use the Dropdown Field in the top left to filter the components by type (e.g. DTR, EDC).
Use the Sort feature ⇅ in the header to sort the components in an ascending or descending order. When using this feature, the affected column header is highlighted.
Select Reset to remove all search queries and filters.
Step 2 - Add Digital Twin Registry
Select Add component.
The new DTR is set up in the dialog.
Select the type DTR.
Fill in the required fields:
Versions - The version of the digital twin registry.
Dataspace - Connect the DTR to the selected dataspace.
Component name - Internal name to identify this digital twin registry.
Display name - This name is displayed in the graphical user interface.
Description - A short description of this digital twin registry.
Company/department name - The name of the organization that is beneficiary of this digital twin registry.
Cost center - Used for identification and billing cost in an organization.
Select Add to create the digital twin registry.
Notice
It is recommended to use the latest version.
Faulty or missing input will result in error messages. Follow the instructions in those messages.
Status of DTRs
The view also displays the status of each DTR.
Status of DTR | Description |
OK | The DTR is working correctly. |
Creating | The DTR is created. This may take a few minutes. |
For more information about a specific DTR and its shell descriptors, see Digital Twin Registry Details.
Next Steps
After adding the DTR, the next step is to Add a Submodel.
