Welcome to the Mapping Service

The Mapping Service can be used for finding mappings (or cross-references) between terms from ontologies, vocabularies and coding standards. It imports mappings from a variety of sources including the Terminology Service and a subset of mappings provided by the UMLS. We're still developing the service so please get in touch if you have any feedback.
