Identifier
An Identifier is a non-encryptable nested entity that is used in the identifiers field of other entities to
uniquely identify them and link them to external resources, as specified in the FHIR documentation.
The Cardinal backend does not enforce the uniqueness of a defined Identifier for any type of entity.
Identifier's system and value can be used to search data using filters.
