Introduction

Vision and Mission Statement

The IRS is providing a technical API Endpoint in the Catena-X Network, which builds an item tree representation of given digital twins stored across the industry. Therefore, it is a key component for the Network to provide data chains along the value chain in the industry.

The vision for the Item Relationship Service is to provide an easy access endpoint for complex distributed digital twins across Catena-X members. It abstracts the access from separated digital twins towards a connected data chain of twins and provides those. It enables to apply business logic on complex distributed digital twins across company borders.

What is the IRS?

Within the Catena-X network, the so-called Item Relationship Service (IRS) forms an essential foundation for various services and products. Within the Catena-X use cases, the IRS serves to increase business value. For example, the IRS provides functionalities to serve requirements, such as occasion-based Traceability, from the Supply Chain Act. In doing so, IDSA and Gaia-X principles, such as data interoperability and sovereignty, are maintained on the Catena-X network and access to dispersed data is enabled. Data chains are established as a common asset.

With the help of the IRS, data chains are to be provided ad-hoc across n-tiers within the Catena-X network. To realize these data chains, the IRS relies on data models of the Traceability use case and provides the federated data chains to customers or applications. Furthermore, the target picture of the IRS includes the enablement of new business areas by means of data chains along the value chain in the automotive industry.

Installation

This section describes both deployment on kubernetes via Helm and local deployment for development.

Helm Deployment

See INSTALL.

Local Deployment

The following subsection provides instructions for running the infrastructure on docker-compose and the application in the IDE.

Start the application with the commands in the subsection further below. After everything is up and running the local IRS API is available at the following URLs:

Docker-compose + IDE

  1. cd local/deployment
  2. Start the necessary infrastructure by running docker-compose up
  3. Start the application from your favorite IDE. For IntelliJ, a run configuration is available in the .run folder.

In case of problems connecting to MinIO check whether the MinIO console is accessible in your webbrowser (see URL in the output of step 2). You might need to wait some time before MinIO is up and accepts connections. If that does not help, execute docker-compose down and repeat from step 2.
