* specifies procedures which are generally applicable to registration at any level of the international OID tree,

* provides guidelines for the establishment and operation of International Registration Authorities for use, when needed, by other ITU-T Recommendations and/or International Standards,

* provides guidelines for additional ITU-T Recommendations and/or International Standards which choose to reference the procedures in ISO/IEC 9834-1:2012,

* provides a recommended fee structure for lower-level Registration Authorities.

Information about registration for specific objects is contained in separate ITU-T Recommendations and/or International Standards.
