Trustworthy data exchange with Gaia-X

In today’s data-driven world, secure and efficient data exchange is a crucial competitive advantage. Companies must be able to integrate and share data from various sources without losing control over their own data. This is where Gaia-X comes in: a flagship project of the European Union that creates a secure, trustworthy, and sovereign data infrastructure for Europe.

In our Research Area Data & Service Ecosystems at CONTACT, we’re working to make the vision of Gaia-X a reality. A key part of this is seamlessly connecting data management systems to Gaia-X-based data spaces.

What is Gaia-X, and why is it important?

In an increasingly globalized and data-driven world, it’s crucial for companies to maintain control over their data while still benefiting from data exchange. Gaia-X provides the framework for this: its core concept for a federated data infrastructure allows platform providers, cloud services, and data holders to communicate and exchange data securely and in compliance with legal requirements.

Gaia-X doesn’t aim to replace existing data infrastructures; instead, it connects them to create an open, interoperable ecosystem. To understand the significance of this shift, it helps to look at the differences between data platforms and data ecosystems:

Data platforms typically operate on a centralized model. Data is copied and uploaded to the platform, allowing other parties to download and use it. The problem with this is that copies of the data exist everywhere, and all participants must trust the platform operator to manage the data securely and correctly.

In contrast to a centralized data platform, in a data and service ecosystem, the operator’s role shifts to that of a federator. This federator offers “federation services” that enable participants to find each other, establish trust, and exchange data directly without a central entity managing or controlling the data.

The core pillars of Gaia-X form the foundation for a trustworthy and future-proof data ecosystem:

  • Trust & transparency: Gaia-X establishes clear rules for data governance, security, and data protection. The system is designed from the ground up to be compliant with the GDPR (General Data Protection Regulation), ensuring user privacy and data security.
  • Interoperability: By adhering to open standards and interfaces, data and services move freely between compliant providers.
  • Portability: Businesses can easily move their data and applications between different Gaia-X-compliant providers without vendor lock-in. This fosters competition and gives companies the flexibility to choose the solutions best suited for their operational needs.
  • Sovereignty: Data sovereignty remains with the owner at all times. Businesses retain control over the access and use of their data, in strict compliance with European laws and values.

Gaia-X is thus an important step towards Europe’s digital sovereignty, offering companies the opportunity to drive innovation, develop new business models, and simultaneously retain control over their valuable data.

Requirements for participating in the Gaia-X ecosystem

Participating in the Gaia-X ecosystem opens up numerous opportunities for companies but also requires fulfilling certain demands.

  • Compliance with the Gaia-X Trust Framework: This includes adherence to rules and guidelines for data governance, data security, data protection, and interoperability.
  • Operating your own infrastructure: Typically, operating your own infrastructure is necessary to ensure full data sovereignty. This might include running an object storage (like S3), a Self-Sovereign Identity (SSI) solution, or other necessary services.
  • Implementation of security measures: Companies must implement appropriate security measures to protect their data and systems from unauthorized access, loss, or damage.
  • Adherence to standards: Gaia-X relies on open standards and interfaces for interoperability between different systems and platforms.

Conclusion

Gaia-X is Europe’s strategic response to the challenges of the digital era. By creating a trustworthy, interoperable, and sovereign data ecosystem, Gaia-X enables companies and organizations not only to securely store their data but also to share it in a controlled manner and use it intelligently.

This not only fosters innovation and new business models across industries but also ensures a fair competitive landscape where even smaller players can benefit from the potential of data-driven value creation. Users and companies regain control over their data, forming the basis for transparency and trust in the digital space.

Sustainability as a competitive edge: one step ahead with PLM

Sustainable thinking is no longer a “nice-to-have” – regulations and customer demands have made it a central pillar of modern innovation. A growing number of companies are realizing that ecological responsibility and economic success can go hand in hand. This is especially evident in product development: where cost-effectiveness used to dominate, sustainability has emerged as another key factor.

The right balance between economic and ecological aspects

While cost and efficiency remain crucial, staying competitive in the future requires taking the environmental balance into account when making business decisions. The challenge lies in finding the right balance between economic performance and ecological responsibility. This is most successful when sustainability is considered from the very beginning – at the design stage – rather than at the very end.

Why the product development process is crucial

Around 80% of a product’s environmental impact is already determined during the development phase. Decisions about materials, manufacturing processes, energy use, and recyclability made during this stage play a decisive role. Leveraging reliable and transparent data in the decision-making process enables companies to lower the environmental impact of their products.

LCA vs. PCF: Two key terms briefly explained

Anyone involved in sustainable product development will inevitably encounter these two concepts:

  • Life Cycle Assessment (LCA): The assessment of a product’s environmental impact throughout its lifecycle, from raw material extraction to disposal.
  • Product Carbon Footprint (PCF): The environmental footprint of a product, expressed in CO₂ equivalents. The PCF is often part of a broader LCA.

Implementing sustainability directly in the PLM system

CONTACT’s sustainability solution allows this environmental data to be recorded and used directly in CIM Database PLM. This enables a systematic evaluation of materials, processes, and product structures. Whether entered manually or imported automatically from environmental databases, a product’s environmental impact can be analyzed and improved directly within the system.

Asset Administration Shell: a key to data exchange in the supply chain?

Sustainability is not a solo effort. Especially for complex products involving multiple suppliers, effective data exchange is crucial. This is where the concept of the Asset Administration Shell (AAS) comes into play – a standardized representation of digital twins for industrial components.

Using AAS submodels like the Carbon Footprint, companies can communicate environmental data in a standardized way, both internally and externally. This creates a seamless data foundation across the entire value chain. Using submodels like the Carbon Footprint, companies can communicate environmental data in a standardized way – both internally and externally, enabling them to integrate data from purchased components.

Three key takeaways:

  1. Sustainability starts with engineering, where crucial decisions are made.
  2. Standardized data formats enable the integration of environmental data into the product lifecycle.
  3. With IT tools like CONTACT Elements Sustainability Cloud, companies can not only plan eco-friendly operations but also implement sustainability early in the development process.

Conclusion

Developing sustainable products is no longer a vision for the future – it’s a reality today. Companies that adopt the right tools at an early stage and rely on standardized processes gain not only ecological advantages but also economic benefits.
