OpenChain

OpenChain is an open standard and associated program that defines requirements for open source license compliance processes within organizations, enabling consistent and auditable open source governance across software supply chains (compliance and governance).

  • Defines a specification for open source license compliance programs within organizations (compliance and governance).
  • Provides a certification framework for organizations to demonstrate conformance to the OpenChain Specification (compliance certification).
  • Offers reference materials, training content, and process templates to support implementation of compliant programs (training and enablement).
  • Focuses on open source license management across the software supply chain, including suppliers and downstream consumers (software supply chain governance).
  • Operates as a Linux Foundation project with a community-driven model for maintaining and evolving the specification (open standards development).

More About OpenChain

OpenChain defines a standard for how organizations structure and operate open source license compliance programs (compliance and governance). The project addresses the problem of inconsistent or ad hoc open source governance across enterprises and their suppliers, which can create legal and operational risk when distributing software that contains open source components. By specifying minimum process requirements, OpenChain provides a common reference for what a quality open source compliance program includes.

The core of OpenChain is the OpenChain Specification (open standard), which sets out process requirements for managing open source licenses within an organization. These requirements cover areas such as documented policies, roles and responsibilities, staff competence and training, review and approval workflows, and record-keeping related to open source usage. The specification is designed so that organizations of different sizes and in different sectors can align their internal procedures with a shared baseline for compliance quality.

OpenChain also provides a certification program (compliance certification) that allows organizations to attest that their open source compliance processes conform to the OpenChain Specification. Certification can apply to an organization as a whole or to specific business units or product lines, depending on how processes are structured. This certification supports clearer communication between suppliers and customers about open source governance practices within the software supply chain.

In addition to the specification and certification, OpenChain maintains supporting materials (training and enablement) such as reference policies, checklists, and training resources to assist organizations in building or improving their open source compliance programs. These materials help operational teams, legal departments, and engineering organizations implement the specification’s requirements in daily workflows, including component intake, license review, attribution preparation, and compliance documentation.

Enterprises use OpenChain in procurement, vendor management, and software development contexts to establish shared expectations for open source governance across internal teams and external suppliers (software supply chain governance). By referencing OpenChain in contracts or supplier requirements, organizations can set a clear process baseline without prescribing specific tools or technical implementations. Within the broader Linux Foundation ecosystem, OpenChain occupies the role of a compliance and process standard focused on open source license management rather than code, protocols, or runtime infrastructure.
