Indicates that the target object is a collection of which the source object is a member. The directed graph induced by this relationship must be acyclic.
tag:ngda.org,2005:relationships/has-member
The inverse of the preceding relationship: indicates that the target object is a member of the source object, which represents a collection. The directed graph induced by this relationship must be acyclic. Collection membership must be represented by member-of relationships; has-member relationships are optional.
