Vocabulary is an important component of all rule modeling projects.  It includes the terms, called entities, referenced by the business rules. In this example, the Vocabulary would contain entities such as “Cargo” and “Aircraft.” You can use Corticon Studio to define and edit Vocabularies.

In your project, you may be responsible for defining the Vocabulary or you may simply use an existing Vocabulary that some else defines. In this example, you will use an existing Vocabulary that is part of the Tutorial sample.

  1. To open the sample Vocabulary file, expand the Tutorial Rule Project, and then double-click Cargo.ecore:


    The Vocabulary opens its editor in the area where all the editors will do their work.

  2. In the Eclipse development environment, you can resize, move, and close tabs and panels to suit your needs. For example, close the Welcome pane and resize other views to get more work area.

  3. Explore the Rule Operators pane. Operators act on elements in the Vocabulary (such as cargo, cargo weight, aircraft, aircraft type, and so on because Corticon Studio comes with a rich set of operators for manipulating data (not unlike the Excel function library).
