| | Introduction to OMG UML |
 | | Three separate parts of UML 2.0 - the Infrastructure (that is, the meta-metamodel), Object Constraint Language, and Diagram Interchange - are still undergoing their first maintenance and will become Available Specifications when this completes. |
 | | That is, the new language goes well beyond the Classes and Objects well-modeled by UML 1.X to add the capability to represent not only behavioral models, but also architectural models, business process and rules, and other models used in many different parts of computing and even non-computing disciplines. |
 | | During the upgrade process, several additions to the language were incorporated into it, including the Object Constraint Language (OCL) and Action Semantics. |
