Feedback

The feedback language aspect defines custom messages to show to the user when an error or a warning is detected in the model.

The FeedbackPerConceptRoot concept is used to define feedback massages for a particular concept. It holds a collection of FeedbackRootMembers which define the condition to check for and a message to show. In addition to using text, the message may refer to the language elements to provide more details about the problem:

• child - the (unexpected) child node that is causing a problem

• link - the link (role) of the problematic child node

• node - the node with the reported problem

• property - a property with a violated constraint

• value - a value that is invalid for a property

• concept - the concept of the target of the invalid reference

• reference - the reference that is out of scope

Additional feedback rules are likely to be added in the future.
