Object Constraint Language (OCL) and Web Ontology Language (OWL) Training Course


Object Constraint Language (OCL) is an expression language that specifies constraints and refines Unified Modeling Language (UML) diagrams to make them understandable for computers. A Web Ontology Language (OWL) is a semantic language that represents rich and complex knowledge about things and their relations.

This instructor-led, live training (online or onsite) is aimed at programmers or anyone who wish to learn and use OCL and OWL for expressing all kinds of model query, manipulation, and specification requirements.

By the end of this training, participants will be able to:

  • Have a better understanding of OCL and OWL architecture.
  • Use OCL and OWL to express model transformations.

Format of the Course

  • Interactive lecture and discussion.
  • Lots of exercises and practice.
  • Hands-on implementation in a live-lab environment.
