Official VDA Recommendation

Material Information - From documents to trusted material data

Increasing regulatory requirements, sustainability reporting and digital validation demand a new level of consistency in material data exchange.

  • Reduce manual re-entry and coordination effort across partners
  • Increase data consistency for compliance, sustainability and audits
  • Enable validated system-to-system exchange with open JSON Schema

A standardized, machine-readable data model designed for digital ecosystems. An open JSON schema enabling interoperable exchange of material and test data across industrial supply chains

Today's reality

Material data exchange across the value chain remains manual, fragmented and error‑prone.

01

Manual process

  • Test planning and documentation
  • Result consolidation and reporting
  • Repeated data entry across system
02

High coordination effort

  • Manufacturers
  • Suppliers
  • Laboratories
03

Quality and Compliance risks

  • Ambiguous interpretations
  • Transcription and formatting errors
  • Costly corrections and rework

The result: fragmented data, limited comparability and increasing regulatory and compliance risk.

The standardized answer

VDA 231-300 and VDA 231-301 - A standardized, machine‑readable foundation for interoperable material data.

01

Consistent material definition

  • Standardized material and surface semantics (VDA 231-300)
  • Clear reference to 3D product data - JT / ISO 14306
  • Unambiguous basis for downstream test and compliance data
02

Interoperable test & measurement data

  • Machine-readable test and measurement results (VDA 231-301)
  • Standardized structure with formal validation rules
  • Direct system-to-system exchange without re-typing
Manufacturers Suppliers Laboratories
03

Shared semantic understanding

  • Common interpretation of material and test data
  • Reduced coordination effort across companies
  • Reliable data exchange

VDA 231‑300 Defines what is tested and how materials are described. VDA 231‑301 Defines how results are structured and exchanged – enabling seamless data flow without re-typing or interpretation gaps.

THE VDA RECOMMENDATION

What is VDA 231-301?

VDA 231‑301 enables interoperable, machine‑readable exchange of material and test data across systems, companies and digital ecosystems.

VDA 231‑301 is an official VDA recommendation defining a standardized, machine‑readable data model for material and test information. It addresses a key challenge in digital supply chains: reliable, interoperable exchange of material‑related data across company and system boundaries.

Built on open JSON Schema, VDA 231‑301 enables validated system‑to‑system data exchange between manufacturers, suppliers and testing laboratories. It builds on the standardized material definitions of VDA 231‑300 and extends them with a machine‑readable model for test and measurement results.

Together, VDA 231‑300 and VDA 231‑301 form a consistent foundation for structured material data exchange. They complement digital ecosystems such as Catena‑X by enabling consistent data flow without proprietary formats, manual re‑entry or interpretation gaps.

While originating from automotive requirements, the data model is generically applicable to any industry relying on structured exchange of material information. The recommendation is developed and maintained by the VDA 231‑301 Project Group through transparent, open collaboration.

Repository Overview

VDA 231‑301 is organized into modular subschema repositories. Each subschema covers a dedicated functional or regulatory domain.

Each subschema addresses a specific functional or regulatory domain and can be used independently or combined depending on the use case.
