Apply now! Expert Group "Exchange Patterns"

Become part of the new Exchange Patterns Expert Group and help shape the reusable exchange patterns that serve as architecture guardrails for the Catena-X Use Case Foundation Layer — consolidating exchange requirements across business domains, reducing fragmentation, and enabling the first exchange-pattern-compliant use cases by Release 27.09.

We are pleased to announce that applications are now open for the new Exchange Patterns Expert Group.

 

Purpose

Today, Catena-X use cases often define data exchange concepts individually, leading to fragmented implementations, limited reuse, and rising complexity as the ecosystem grows. The Exchange Patterns Expert Group will establish a common set of reusable exchange patterns as architecture guardrails — a key element of the Catena-X Use Case Foundation Layer — ensuring a consistent approach to data exchange across all business domains and use cases.

 

Key Goals

  • Reusable Exchange Patterns: Translate common exchange requirements into standardised, reusable patterns that become the preferred approach for interoperable Catena-X solutions.
  • Alignment with Semantics: Coordinate closely with the Semantics Expert Group to ensure exchange and semantic requirements evolve consistently.
  • First Compliant Use Cases: Establish the first exchange-pattern-compliant use cases by Release 27.09.

 

Deliverables

  1. Definition of the Catena-X Exchange Pattern Framework and its architecture guardrails.
  2. Consolidation of exchange requirements into reusable patterns across business domains.
  3. Governance and guidance on pattern selection and compliance during the release process.
  4. Migration support for existing use cases towards approved patterns.
  5. Alignment with Semantics experts on exchange, semantic, and implementation considerations.
  6. A stable integration foundation abstracting from technical protocols for resilient, reliable components.

 

Why participate?

  • Direct Influence: Shape how data exchange is designed and standardised across Catena-X.
  • Foundational Impact: Contribute to the Use Case Foundation Layer — improving interoperability, accelerating adoption, and increasing reuse.
  • Unique Opportunity: Influence a capability that will affect every future Catena-X use case and enable scaling.

 

Who should apply?

Experts with strong expertise in at least one of the following:

  • Catena-X Knowledge: Architecture principles, standards, and core concepts.
  • Implementation Experience: Hands-on Catena-X use case implementation, ideally with interoperability and data exchange insight.
  • Use Case Architecture: Designing, evaluating, or standardising data exchange concepts.
  • Integration Expertise: API design, messaging, event-driven architectures, idempotency, and operational resilience.

 

Commitment

A significant time commitment is expected throughout the next year, including intensive working sessions and one or more multi-day workshops during 2026, starting in September, alongside regular meetings.
