Binding traits to case nodes
Case management systems and techniques are disclosed. In various embodiments, for each of a plurality of case nodes comprising a case model a trait definition comprising a corresponding set of traits associated with that case node is received. The respective trait definitions are used to bind each set of traits to the case node with which the set of traits is associated in case instances created based on the case model.
