Hi CoRE

https://github.com/OpenMobileAlliance/OMA_LwM2M_for_Developers/issues/482

There is opening issue in OMA LwM2M Developer forum about URI scheme in NB-IoT Non-IP Data Delivery transport. As proposal mentioned in issue page that since there are no hosts in the 3GPP CIoT NIDD architecture, the host portion is optional.

For example:

  *   coap+nidd:/// - empty Uri-Path and Uri-Query
  *   coap+nidd:///uri/path - two Uri-Path options will be sent, uri and path
  *   coap+nidd:///?uri=query - one Uri-Query option will be sent, uri=query

There is another relevant draft proposal in CoRE, link is https://datatracker.ietf.org/doc/html/draft-amsuess-core-transport-indication-03

Could you help to advise, what would be proper way to represent URI in NB-IoT Non-IP Data Delivery transport?
Thanks.
