|  description | The US Core RelatedPerson Profile inherits from the FHIR [RelatedPerson](https://hl7.org/fhir/R4/relatedperson.html) resource; refer to it for scope and usage definitions. This profile sets minimum expectations for the RelatedPerson resource to record, search, and fetch basic administrative information about persons with a legal or familial relationship to a patient. It specifies which core elements, extensions, vocabularies, and value sets **SHALL** be present and constrains how the elements are used. Providing the floor for standards development for specific use cases promotes interoperability and adoption. | This profile represents a person participating as a witness for a person's advance directives. |
