Meta Tags & Security Labels

FHIR resources in the Health Gorilla API support the use of meta.tag and meta.security for tagging, filtering, and access control.

Example

{
  "meta": {
    "tag": [
      {
        "system": "http://example.org/tag-system",
        "code": "research",
        "display": "Research Data"
      }
    ],
    "security": [
      {
        "system": "http://hl7.org/fhir/v3/Confidentiality",
        "code": "R",
        "display": "Restricted"
      }
    ]
  }
}
