The Linux Foundation Creates the Appia Foundation to Establish Standardized Specifications Across the AI Value Chain

The Linux Foundation, the nonprofit organization enabling mass innovation through open source, announced the formation of the Appia Foundation, hosted under the Joint Development Foundation (JDF)—enabling the establishment of modular specifications that provide a connecting layer to bridge foundational global standards with practical, trusted assessments across the global AI value chain.

According to the Linux Foundation, regulations around the world are moving to active enforcement, and value chain partners require evidence of trustworthy AI in contracts and vendor evaluations. International frameworks such as ISO/IEC standards establish vital foundations, and they unlock a powerful opportunity for a consistent, shared mechanism to translate these global rules into practical, verifiable proof.

To address this, the Appia Foundation delivers an open connecting layer by building on international standards and established frameworks to develop publicly available global specifications.

The Appia specifications are organized across a Requirements and Guidance layer and an Assessment Enablement layer. These specifications provide the testing criteria, evaluation guidelines, and component typologies needed to effectively assess AI models, systems, applications, and processes, the Foundation said.

"As international standards and legal frameworks become more established, global organizations need a consistent, practical way to verify that AI systems conform to new expectations," said Jim Zemlin, CEO of the Linux Foundation. "The Appia Foundation establishes a neutrally governed environment where the entire industry can collaborate on a common assessment framework. By building this infrastructure in the open, we are helping organizations reduce complexity, lower operational costs and build trust."

The Appia specification architecture is designed for functional modularity and evidence pass-through. Instead of assessing an entire system from scratch, organizations evaluate only what is relevant to their role, component, and regulatory context.

When an upstream provider demonstrates conformity with relevant modules, that technical evidence passes through to downstream users. This enables seamless reuse of conformity evidence across the value chain, reducing friction while maintaining clear boundaries of accountability, the Foundation said.

“AI systems now make decisions about people's loans, their children's schools and their jobs. People on the receiving end deserve to know those systems were built and assessed against criteria that hold up to scrutiny,” said Craig Shank, executive director of the Appia Foundation. “The Appia Foundation was formed to do that work: creating publicly available specifications that organizations across the AI value chain use to demonstrate their systems meet those criteria. By establishing this open framework, we are building the accountability layer required to scale safe and trusted AI across major industries.”

Initial members of the Appia Foundation include Arm, Armilla AI, Ericsson, Google, Mastercard, Microsoft, Mitsubishi Electric, Naaia, Nemko, Omron, OpenAI, Schneider Electric and Siemens.
