The '''Object Constraint Language (OCL)''' is a [[wikipedia:Declarative_programming|declarative language]] for describing rules that apply to [[UML School|Unified Modeling Language (UML)]] models developed at IBM and now part of the UML standard. Initially, OCL was only a formal specification language extension to UML. OCL may now be used with any Meta-Object Facility (MOF) Object Management Group (OMG) meta-model, including UML. The Object Constraint Language is a precise text language that provides constraint and object query expressions on any MOF model or meta-model that cannot otherwise be expressed by diagrammatic notation. OCL is a key component of the new OMG standard recommendation for transforming models, the Queries/Views/Transformations (QVT) specification. ==== [[Part 1 OCL Common Expressions]] ==== ==== [[Part 2 OCL: Operators]] ==== ==== [[Part 3 OCL: Derivation properties]] ==== [[Category:OCL]] [[Category:Beginner]] Return to OCL Expressions.
