The workgroups of the OI4 Alliance are the technical backbone of our community, driving the development, integration, and standardization of solutions that enable interoperability across industries.

They provide a structured approach to address challenges in Industry 4.0, ensuring companies can efficiently implement digital solutions.

By bringing industry leaders, suppliers, and operators together, our workgroups translate real-world challenges into organized, collaborative efforts that lead to practical and scalable solutions.

Our current workgroups are:

Making calibration trustworthy, structured, and machine-readable

Calibration certificates today are often issued as PDFs or paper documents — useful for humans, but not for machines. The DCC via AAS demonstrator transforms calibration data into structured, authenticated, and interoperable digital form, enabling seamless exchange across companies and systems.

In our demonstrator, each measurement instrument is represented by an AAS (Asset Administration Shell). The calibration result is stored in a standardized digital calibration certificate submodel. The certificate is signed, versioned, and securely shared — so downstream systems can consume and trust the data automatically.

Key capabilities:

• Machine-readable calibration data instead of manual conversion

• Secure, signed calibration certificates ensuring data integrity

• Automatic integration of calibration results into workflows and quality systems

• Cross-company interoperability without custom interfaces

Why it matters
With the DCC demonstrator, we close the gap between measurement and automation. No more manual re-entry of calibration data, no ambiguity in interpretation, and no isolated silos. Metrology, quality, and automation systems all benefit. Manufacturers, calibration labs, and system integrators gain a trusted, scalable path to digital calibration — one that fits into broader industry 4.0 architectures.

A complete product story – from creation to ownership and change

In this demonstrator, a production of a bicycle takes shape — not just physically, but digitally.
Each component, from frame to saddle, is represented by its own Asset Administration Shell (AAS). Together, they form the foundation for a Digital Product Passport (DPP) that grows automatically as the product evolves.

Visitors can experience how data flows through the entire lifecycle:

• Digital Product Passport (DPP): All relevant information — technical data, materials, and sustainability parameters — are stored in the AAS. As the product takes shape, the DPP builds itself automatically.

• AAS Transfer of Ownership: When the bicycle is handed over to a new owner, its digital twin moves with it. The AAS, including all relevant submodels, is securely transferred across company boundaries, maintaining data integrity and access control.

• AAS Product Change Notification (PCN): If a component changes — for example, a new handlebar design — the update is published automatically via an AAS submodel. Stakeholders are notified instantly, and downstream systems can react without manual effort.

Why it matters
This demonstrator shows how the Asset Administration Shell can connect processes and partners along a product’s lifecycle — from production to use and back. What was once fragmented data becomes a continuous, trusted information flow.

The result: transparent products, seamless handovers, and structured change communication — all built on open standards.
