Retrieving Source-Asserted Parents and Children

URIs | Query Parameters | Sample Output

URIs with /parents or /children support the following use cases:

  • Retrieve the immediate parents of a known source asserted identifier.
  • Retrieve all immediate children of a known source asserted identifier.

Note that ‘current’ in the URI can always be used to search against the latest UMLS publication.
You may use any valid UMLS release back to 2008AA in your URI if you would like to search against a particular version of the UMLS.

URIs

The base URI is https://uts-ws.nlm.nih.gov/rest

Sample URI Description Returned JSON Object classType
/content/current/source/SNOMEDCT_US/9468002/parents Retrieves parents a source-asserted identifier SourceAtomCluster*
/content/current/source/SNOMEDCT_US/9468002/children Retrieves children of a source-asserted identifier SourceAtomCluster*

*Calls using codes from HL7V2.5 and HL7V3.0 return output with an “Atom” JSON Object classType.
