A set of mapping tools have been created to assist with the assignment, verification, integration, export and import of mappings between two ontologies. In version 1.1 we add the ability to automate mappings to any UMLS ontology using the UMLS MetaMap.
The need for Mapping tools
The Mapping tools were created to assist in the use case where you need to merge one or more sets of ontology terms into another. Typical use cases are such as that found in federated query systems, e.g. SHRINE, where the ontology to use is dictated to you by another party and you have terms that do not align readily to the dictated ontology. For example the ontology might specify medication terms as RxNorm and your local ontology uses NDC or you may have extensive local terms and codes that have to be aligned.
