Re: [coman] are we there yet?

Hi,

We are just completing a new OMA Lightweight M2M standard which includes an efficient Object system for managing constrained devices over CoAP. It has a highly optimised form of Object format which is applicable for device management, network management and also application data. If you are interested, I will present more information about this new standard at the CoRE meeting on Wednesday. 

Taking this into account, I definitely do not believe there is a need to develop new protocols to manage these device. The whole point is that we need to use the same protocol for management and the application. 

The OMA Lightweight activity only defines a standard set of device, connectivity, firmware and location objects. The IPSO Alliance is working on some application data Objects. Therefore I would see a need for an IETF effort to help define more Objects for the purpose of managing constrained devices and networks, which could then be registered with the OMA registry. 

Regards,
Zach
