ISO/IEC 5230 defines the key requirements of a quality open source license compliance program




How Does ISO/IEC 5230 Work?

ISO/IEC 5230 helps organizations manage open source licensing requirements for past, current and future products or services.

ISO/IEC 5230 identifies:

  1. The key places to have license compliance processes
  2. How to assign roles and responsibilities
  3. And how to ensure sustainability of the processes

ISO/IEC 5230 is lightweight, easy to read and is supported by our global community with free reference material and conformance resources.
