Obtaining raw value when using query options instead of IDs

[ghost]

The SensorThings API offers a path segment $value at the end of the URL in order to retrieve the raw value of a property. An example of this can be found here:

• URL: https://toronto-bike-snapshot.sensorup.com/v1.0/Datastreams(206051)/Observations(1595467)/result/$value

• Response

23

However, I would like to have a path segment or query option that allows me to obtain raw values from queries of multiple rows. For example, if someone wants to get the latest observation value for a datastream, the object returned is not the raw value, but a JSON Object containing more properties.

To clarify, here is also an example of such an object.

• URL: https://toronto-bike-snapshot.sensorup.com/v1.0/Datastreams(206051)/Observations?$top=1&$orderby=phenomenonTime%20desc&$select=result

• Response

  {
  @iot.count: 3511,
  @iot.nextLink: "https://toronto-bike-snapshot.sensorup.com/v1.0/Datastreams(206051)/Observations?$orderby=phenomenonTime%20desc&$select=result&$top=1&$skip=1",
  value: [
  {
    result: "23"
  }
  ]
  }

  However, I would like to obtain only the raw value as in the first example:

23

Is there any way to achieve this?

Thanks!
