Hi,

today ends the call for this draft. 
The feedback has been positive from all reviewers and it looks the
document is ready to move forward. 

One small nit however is the "rpm" unit, which seems to be already
registered in the main senml registry under the "1/min" name. 
In order to avoid duplication we probably should have one only. 
While OMA folks are making a decission we could simply move this draft forward
without that unit, which they could add afterwars.

Therefore, if the authors and the group are OK with that nit, the
authors can resubmit and we will finalize the WGLC here.

Best Regards,
-- Jaime Jiménez

I have slightly cleaned up the above and put it into the editor’s draft https://core-wg.github.io/senml-more-units/draft-ietf-core-senml-more-units.html (*); diff can be seen below or (together with some previous changes) at https://tinyurl.com/senml-more-units-diff .
