Working features

The following features are working:

• Hosting a basic IS-04 node api with only node and device resources
• Advertising the IS-12 control endpoint (urn:x-nmos:control:ncp/v1.0) inside the IS-04 device resource
• Hosting a WebSocket server which the IS-12 endpoint uses for bidirectional communication
• Receiving Command messages and sending Command Response messages by pairing their handles (IS-12 messages)
• Receiving Subscription messages and sending Notification messages whenever object properties change (IS-12 schemas)
• Offering a basic NcObject implementation
  • Implementing the generic Get method of any object to retrieve the value of any property (NcObject)
  • Implementing the generic Set method of any object to set the value of any property (NcObject)
• Offering an NcBlock implementation and advertising a root block and nested block
  • Implementing all NcBlock methods
• Offering a Class Manager implementation
  • Implementing class discovery
  • Implementing datatype discovery

To do

The following features are planned:

• Implementing the IS-04 registration workflow so we can register resources in an NMOS registry and maintain the registrations via heartbeats
• Implementing the NcReceiverMonitor model
• Implementing the NcSenderMonitor model
• Implementing the IS-05 connection management api with senders and receivers being monitored by associated sender and receiver monitors with appropriate touchpoints
• Implementing the BCP-008-01 behaviour in regards to activation, status reporting delay, overall status mapping and transition counters
• Implementing the BCP-008-02 behaviour in regards to activation, status reporting delay, overall status mapping and transition counters
• Implementing a vendor specific class
