"In 1997, UML was adopted as a standard by the Object Management Group (OMG), and has been managed by this organization ever since. In 2005, UML was also published by the International Organization for Standardization (ISO) as an approved ISO standard.[2] Since then the standard has been periodically revised to cover the latest revision of UML.[3]"
