public interface PropagationConstraint
extends Property

At any time entities and relations can be added or removed to/from a context or deleted. The PropagationConstraint property contained in each relation is a predefined Property type which indicates the behaviour to be held on a target entity when an event related to a context occurs in the source resource or directly to the relation. The default values of propagation constraints are: - IsRelatedTo: remove=keep, add=unpropagate; - ConsistsOf : remove=cascadeWhenOrphan, add=propagate. https://wiki.gcube-system.org/gcube/Facet_Based_Resource_Model#Propagation_Constraint
