What is Object Constraint Language (OCL)?..

Answer / guest

The Object Constraint Language is a declarative language
for describing rules that apply to 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 OMG
metamodel, including UML. The Object Constraint Language is
a precise text language that provides constraint and object
query expressions on any Meta-Object Facility model or
metamodel that cannot otherwise be expressed by
diagrammatic notation. OCL is a key component of the new
OMG standard recommendation for transforming models, the
QVT specification.
