Further SNOMED International maps are under development or in field trials such as
Each SNOMED CT Concept (except the root concept) has a relationship to one or more parent concepts. Each of these parent concepts represents a more general clinical meaning (known as a supertype). The resultant network of relationships is more than a simple tree and forms a logical structure known as a polyhierarchy
More precisely the |is-a| relationship polyhierarchy is a Directed Acyclic Graph [DAG]
. This structure makes it possible to represent meaning in a more complete way than is possible in a simple hierarchy.
