Entity transient_association

• An association of two or more things, identified by the things and the time or time period for which the association is of interest. Transient associations often represent the state of one thing with respect to another. The state of interest may be caused or terminated by activities, for example, storage of a product in a tank would be a transient association between tank and product, caused and terminated by transfer activities.
