Guide to the Meta Model Reference

The Essential Meta Model Reference provides detailed description of every meta class and the relationships between them. Each class is presented in a fully hyperlinked page, enabling you to navigate the meta model documentation rapidly.

The following diagram shows a typical class - in this case the Business Logical abstract class.

The following information is provided for every class:

• Documentation - a description of the of the meta class and its purpose
• Superclasses - lists the parent classes of this meta class in the hierarchy
• Subclasses - lists the specialisation classes of this meta class
• Types - always :STANDARD-CLASS
• Template Slots - the list of attributes and relationships that belong to this class. These correspond to the fields that appear on each Form field in Protege. Each attribute is defined in terms of:
  • Slot Name - the name of the attribute
  • Documentation - a description of the purpose of the attribute
  • Type - the type of element that is held in this attribute. Many of these are click-able, enabling you to find out more information about that type.
  • Cardinality - How many instances of the specified type can be held in this attribute
  • Default - describes any default values that this attribute has.
