Re: [apps-discuss] SenML

Hi,

I have a question on EXI use.

Is it practical to allow both strict (SHOULD) and non-strict (MAY) ?

In this case, some nodes may not have non-strict grammar. So, nonstrict-capable-and-extended-sender and strict-no-extension-receiver must make some agreement to make a communication in strict mode.

IMHO, I like strict schema-informed (because it can reduce or eliminate dynamic memory allocation).

Regards,

Yusuke

The goal is to define a base data format that sensors and other Internet of Things devices can easily use, preferably without having to define entirely new schemes and different structures just to measure a slightly different thing.
