API Reference

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"
    }
  ]
}

Use Cases

  • Apply security labels to control access
  • Tag data for workflow or reporting purposes
  • Filter resources using _tag and _security parameters
