# Provenance when writing vital sign data

### 1. Provenance data around who authored the observation (e.g., the health system in patient mediated data from a healthcare provider)

[{
  "resourceType": "Provenance",
  "id": "contained_1",
  "target": [{"reference": "#"}],
  "recorded": "2019-07-09T15:26:23.217+00:00",
  "agent": [{
    "type": {
      "coding": [{
        "system": "http://terminology.hl7.org/CodeSystem/provenance-participant-type",
        "code": "author",
        "display": "Author"
      }]
    },
    "who": {
      "display": "Saint Luke\'s Hospital of Kansas City",
      // identifier could be an url as in Patient Access Brands

        "value": "https://stlukes.example.org"
      }

      }]
    },
    "who": {
      //this is the user submitting the data
      //can be populated by the EHR based on the SMART context if omitted
      "reference": "Patient/123"
    }
  }]
}]
