The AIM Workhub System permits Associations to be created only where that Association has been pre-defined as a Permissible Association between objects of such classes. Any of the classes, both Essential and Incidental classifications, contribute to the set of Permissible Associations between two objects.
A Permissible Association is defined in the Class Library as an Association between two classes:
In this example, any object of type DOCUMENT CONTENT may have a ‘refers to’ Association to any Object of type EQUIPMENT. However, this does not automatically permit the Association in the reverse direction. If this is required (unlikely in this case), a second Permissible Association must be created.

Permissible Associations between Classes are inherited by their subclasses.
Note: For the AIM Dashboard to function properly, all documents should be subclassed directly or indirectly from DOCUMENT CONTENT even in a customized Class Library. Thus, the references to Association above would be permitted for all document types.
