Service statistics in GraphQL API

The user can retrieve:

per day Vehicle Journeys count “Service counts” for a date range for Line(s)
total Vehicle Journeys count “Service count” for a date range for Line(s)

Example 1: Retrieve daily statistics

{
  lines {
    nodes {
      objectid
      serviceCounts(from: "2021-01-01", to: "2021-01-31") {
        date
        count
      }
    }
}

{
  "data": {
    "lines": {
      "nodes": [
        {
          "objectid": "chouette:Line:d1b1f581-8b68-456c-8de8-714c142a8ec9:LOC",
          "serviceCounts": {
            "nodes": [
              {
                date: "2021-01-01",
                count: 17,
              },
              {
                date: "2021-01-02",
                count: 33,
              },
              ...
              {
                date: "2021-01-31",
                count: 35,
              },
            ]
        }
        {
           "objectid": "chouette:Line:d1b1f581-8b68-456c-8de8-714c142a8ec9:LOC",
           "serviceCounts": {
              "nodes": [
                {
                  date: "2021-01-01",
                  count: 67,
                },
                ...
              ]
           }
        }
      ]
    }
  }
}

Example 2: Retrieve total count

{
  lines {
    nodes {
      objectid
      serviceCount(from: "2021-01-01", to: "2021-01-31")
    }
}

The syntax to define a such substitution is: %{objectid//pattern/replacement}.

Example

generator identifier: prefix:%{objectid//:/_}
objectid value: x:y:z
resulted identifier: prefix:x_y_z

Include Direction Name in VehicleMonitoring SIRI Lite response
