What's inside Item Relationship Service

  2. Overview of the Model Based Development and Data Processing (MDP) Kit

    The Model Based Development and Data Processing (MDP) Kit provides a framework for the exchange and collaborative use of simulation models and data services across the automotive industry. It enables the generation of physically precise overall models during the design phase and the post-processing of operational data via data services (such as scripts and simulation models) without compromising the intellectual property of the model owner. The solution is built upon the existing Connector KIT (EDC).

  3. Overview of Logistics Carbon Footprint (LCF) Accounting

    Logistics Carbon Footprint (LCF) is a critical component of the overall Product Carbon Footprint (PCF). Accurate LCF accounting requires collaboration between three primary actors to overcome information asymmetry: Suppliers (who have dispatch notes), Logistics Service Providers (who have actual transport execution and emission data), and Customers (who receive the goods). A dedicated logistics platform is used to securely exchange this data to enable precise, standardized emission calculations.

  4. Overview of Industry Core Kit Aspect Models

    The Industry Core Kit defines specific aspect models that must be attached to Digital Twins of type PartType or PartInstance. These models are governed by Catena-X standards.

  5. Overview of the Supply Chain Disruption Notifications kit

    The Supply Chain Disruption Notifications kit provides standards and resources for implementing notification exchanges within the Catena-X dataspace. The Development View is organized into the following key areas:

    • Architecture: Describes the interactions between components in the notification context.
    • Policies: Details access policies, usage policies, and contract definitions.
    • Protocol: Provides examples for registering data assets in the connector.
    • Sample Data: Defines the semantic data model using turtle files and JSON payloads.
    • Operation View: Contains quick installation guides and references to ready-made implementations.

  6. Overview of PCF Data Acquisition Architecture using AAS

    The PCF Data Acquisition architecture is designed to collect data from shop floor and IT systems to calculate Product Carbon Footprint (PCF) values in compliance with the Catena-X PCF Rule Book.

    Key components include:

    • Shop Floor Layer: Machines and smart meters providing energy/material consumption via OPC-UA and Modbus-TCP.
    • Industry Information Hub (IIH) & Aggregation App: Runs on Siemens Edge Devices; IIH collects machine data, and the Aggregation App forwards it via REST-API.
    • AAS Server (AssetFox): Central manager for Asset Administration Shells (AAS), processing time series data and interfacing with AssetFox SaaS and M-X Port Leo.
    • ERP System: The central hub exchanging data with the AAS Server, EnFlex Optimizer, and AAS Creator Service. It combines production and energy data.
    • AAS Creator Service: Generates AAS files using predefined submodels.
    • EnFlex Optimizer: Optimizes electricity procurement costs based on the Bill of Process (BOP) and flexibility parameters.
    • External Interfaces: SiGreen Cloud (receives production results via REST-API) and Energy-Charts (provides electricity price data).

  7. Overview of the Geometry KIT

    The Geometry KIT is designed to enable the secure and sovereign exchange of engineering geometry information (such as CAD models and associated metadata from Data-Management-Systems) across the Catena-X value chain. It provides a standards-based foundation for interoperability, ensuring that 3D assets are discoverable, accessible, and reusable without compromising data sovereignty. The kit bundles Catena-X standards, profiles, APIs, semantic models, and reference implementations to facilitate the publishing, discovery, requesting, and consumption of geometry data, specifically mapping data from enterprise PLM/CAE systems into Catena-X-compliant representations.

  8. Overview of Traceability Kit Architecture

    The Traceability Kit is built upon several Catena-X core components and standards. To implement or integrate with Traceability, developers must be familiar with:

    • Industry Core: For digital twins and aspect models.
    • Asset Administration Shell (AAS): The underlying standard for digital twins.
    • Digital Twin Registry (DTR): The service used to store, publish, and search digital twins.
    • Connector (e.g., Tractus-X EDC): The central data sharing infrastructure based on Eclipse Dataspace Components (EDC).
    • Item Relationship Service: Used for traversing digital twin data chains via Data Chain Templates.
    • EDC Discovery: Used to locate the EDC of a Catena-X partner.
    • SAMM: The modeling standard for aspect models.

  9. Overview of the Digital Twin Kit

    The Digital Twin Kit provides a uniform infrastructure for the Catena-X Automotive Network to enable data-level interoperability between Business Partners. Its primary goal is to trace parts and materials across the entire value chain (n-tier levels) without compromising data sovereignty. It bundles standards, APIs, interaction patterns, and reference implementations for building Digital Twins of assets throughout their lifecycle. It is designed to integrate seamlessly with the Connector KIT.

  10. Overview of Autonomous Operation and Remote Services for Error Handling

    The Autonomous Operation and Remote Services framework aims to maximize machine utilization by ensuring continuous operation through remote control, maintenance, and troubleshooting. The process involves monitoring machine and fault data (machine status, process, and operational data) shared via MX-Port Hercules and Orion. Corrective actions are triggered by AAS Operations and executed by the Machine Owner using OPC UA-based skills for parameterization and execution of production processes.

  11. Overview of the Logistics KIT

    The Logistics KIT extends the digitally represented value chain of parts, batches, and vehicles to include the transport path. It enables the exchange of transport information (such as geo-data, bundling of parts/batches in transport units, and logistics service provider data) in an n-way relationship between manufacturers, Tier-N suppliers, and logistics service providers (LSPs). The goal is to reduce interfaces, improve quality issue tracking, and provide environmental data like CO2 emissions using Catena-X and Gaia-X principles.

  12. Overview of the Traceability KIT

    The Traceability KIT (v26.03) enables application and data providers to trace parts and materials across the entire value chain while maintaining data sovereignty. It provides the standards, aspect models, digital twins, APIs, and processes necessary to develop traceability apps. It is built upon Catena-X standards, specifically requiring the Industry Core KIT "Part Instance" as a mandatory prerequisite to establish the data chain for vehicles, parts, and materials.
