COOM Profile: CORE

Synopsis

The COOM Core profile offers the language elements needed to define the most basic configuration knowledge base. A product can be defined by structures and enumerations of predefined choice values. Dependencies between the choice values of the enumeration elements are introduced by using constraints (bidirectional). These constraints define either allowed or forbidden combinations of choice values.

Building Blocks

• Product definition
• Enumerations
• Constraints on choice values

Example: Kids Bike

The product KidsBike offers the configurable elements color, wheelSize, and a supportWheels. It is important, that supportWheels is only possible for the small wheel sizes W14 and W16. Also, the color Yellow is only allowed for the larger wheel sizes W18 and W20.
