Open Standards Compliance

Compliance Levels

To assist governments and other bodies in recognizing and adopting standards that conform to this Requirement, the OSI defines two levels of compliance:

OSR Compatible

This indicates that the owner of the standard has self-certified that their standard complies with this Requirement, and all Compliance Criteria. Anyone may ask the OSI to review an OSR Compatible standard; if the OSI finds that the standard is incompatible, the owner must either modify the standard or stop using the OSR Compatible mark.

OSR Conformant

This indicates the OSI has reviewed a standard, as submitted by the owner, and certified that it fully conforms to the OSR. The OSI may charge a fee to offset the costs of this certification.


The OSI may, at its sole discretion, update the Criteria from time to time to ensure they continue to fulfill the intent of the Requirement. These updates will include an explicit version number, and the most current version will always be available from

To promote and protect open source software and communities...

For over 20 years the Open Source Initiative (OSI) has worked to raise awareness and adoption of open source software, and build bridges between open source communities of practice. As a global non-profit, the OSI champions software freedom in society through education, collaboration, and infrastructure, stewarding the Open Source Definition (OSD), and preventing abuse of the ideals and ethos inherent to the open source movement.

Open source software is made by many people and distributed under an OSD-compliant license which grants all the rights to use, study, change, and share the software in modified and unmodified form. Software freedom is essential to enabling community development of open source software.
