Validation Rules

Model Validation works against a set of validation rules, arranged in the following groups:

  • (Element, Relationship, Feature, Diagram): Well-Formedness
    Checks whether or not an element, relationship, feature or diagram is well-formed; this group of rules includes checks such as whether the item is a valid UML item and whether a diagram contains valid elements within it
  • Element: Composition
    Checks whether or not a UML element contains valid children, whether it contains the right number of valid children, and whether or not the element is missing any required children
  • (Element, Relationship, Feature): Property Validity
    Checks whether or not the item has the correct UML properties defined, and whether the properties contain incorrect or conflicting values
  • (Element, Relationship, Feature): Custom Properties
    Validates an item against any defined constraints in OCL
