Metadata that describes the ArcGIS stream service. This property is null by default and is populated when the data source loads.

Once the data source is loaded, you can use this metadata to find things like:

  • Fields: Field definitions for data in the stream

  • Track ID field: The field that contains a unique ID for each track in a track-aware service

  • Archive service URL: A service that contains the latest observations for dynamic entities provided by this stream
