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. Versioning 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 http://opensource.org/osr/.
