No more than 64 labels can be associated with a given store.

An object containing a list of "key": value pairs. Example: { "name": "wrench", "mass": "1.3kg", "count": "3" }.

{
  "segments": [
    {
      object(Segment)
    }
  ]
}
Fields
segments[]

object(Segment)

Segment

A segment in a structured format.

    string: string,
    ...
  }
}
Fields
segmentId

string

A string that indicates the type of segment. For example, EVN or PID.

string

Set ID for segments that can be in a set. This can be empty if it's missing or isn't applicable.

fields

map (key: string, value: string)

A mapping from the positional location to the value. The key string uses zero-based indexes separated by dots to identify Fields, components and sub-components. A bracket notation is also used to identify different instances of a repeated field. Regex for key: (\d+)([\d+])?(.\d+)?(.\d+)?

Examples of (key, value) pairs:

  • (0.1, "hemoglobin") denotes that the first component of Field 0 has the value "hemoglobin".

  • (1.1.2, "CBC") denotes that the second sub-component of the first component of Field 1 has the value "CBC".

  • (1[0].1, "HbA1c") denotes that the first component of the first Instance of Field 1, which is repeated, has the value "HbA1c".

An object containing a list of "key": value pairs. Example: { "name": "wrench", "mass": "1.3kg", "count": "3" }.

SchematizedData

The content of an HL7v2 message in a structured format as specified by a schema.

JSON representation
{

  // Union field result can be only one of the following:
