Model validation

The psl.validation project contains a set of constraints in EVL, which implement more complex validation logic that cannot be encoded in the metamodel (e.g. that the start month and the duration of a task are positive numbers, that all persons participate in at least one task). To run these constraints, introduce an error into one of your diagrams (e.g. make the start month of a task a negative number or add a person to the project that does not contribute to any task) and then select the Diagram -> Validate menu. An error/warning marker should be added to the offending element as shown below.

Resources

The editor's custom icons were borrowed from the archi tool.
