}This example documents a normalized shape; it does not establish that a FHIR endpoint or bulk export is available for this catalog entry. When a record includes _source, _methodology, snapshot-date, or confidence fields, those fields are nullable and delivery surfaces can return different subsets. Published bulk files are listed separately in the bulk manifest.
Fields in this record
What each field in the illustrative MedicationKnowledge mapping means.
The fields below are derived from the displayed illustrative FHIR MedicationKnowledge mapping. When a record includes source-metadata fields (_source, _methodology, and a snapshot date), they describe that delivered record. Those fields are nullable and may be absent from a response; identity fields key the record and data fields carry the measured values.
