Official VDA Recommendation
Increasing regulatory requirements, sustainability reporting and digital validation demand a new level of consistency in material data exchange.
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
The result: fragmented data, limited comparability and increasing regulatory and compliance risk.
The standardized answer
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
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.
Get involved
VDA 231‑301 provides a standardized, machine‑readable data model for material and test information, enabling interoperable data exchange across organizations and IT systems. Replace document‑based processes with validated, system‑to‑system data exchange. Integrate the open JSON Schema into your platforms and toolchains to reduce manual effort, improve data quality and ensure reliable compliance and sustainability reporting at scale. VDA 231‑301 is developed as an open standard. Adoption, technical feedback and real‑world use cases directly shape its evolution. Join the community to contribute expertise, integrate the standard into your systems and drive long‑term interoperability across value chains.
Quick start: explore the schema, validate example files and test interoperable material data — directly in your browser.
OPEN PROJECT RESOURCES
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.
