  - name: Data Streams
    description: |-
      Datastreams allow access to observations produced by systems, in various formats.
      They also provide metadata describing the exact meaning of properties included in the observations.

      API clients can act both as sender of receiver of observations.

  - name: Observations
    description: |-
      Access to historical and real-time observations.

  - name: Control Streams
    description: |-
      Control channels (or control streams) allow sending commands to systems, in various formats.
      They also provide metadata describing the exact meaning and content of command messages.

      API clients can act both as sender or receiver of commands.

  - name: Commands
    description: |-
      Access to historical and real-time commands.

  - name: System Events
    description: |-
      System events are used to notify users of changes to one or more systems.

  - name: System History
    description: |-
      Advanced access to historical system descriptions.
