Hi all,

Mid June I submitted a draft that introduces the concept of a local basename to SenML.

Here is the draft:
https://tools.ietf.org/html/draft-tschofenig-core-senml-lbn-00

In the work on LwM2M we make use of SenML but only recently we noticed that there is a mismatch between the examples in the LwM2M specification and the published SenML draft.
We just didn't realize that the authors of SenML had the expectation that each sensor reading would be globally identifiable. While this feature may be useful in certain contexts it is a problem in the LwM2M context where we actually care about smaller payload sizes.

>From an over-the-wire optimization potential this simple extension is just fantastic. Even with a small number of sensor readings sent by IoT devices you can gain huge benefits.

Ciao
Hannes
