Re: [T2TRG] Schema conversion opportunity: OMA LWM2M objects to YANG?

Could you please provide a pointer to the DSL to which you are referring?

Thanks :)

Subject: [T2TRG] Schema conversion opportunity: OMA LWM2M objects to YANG?

Around the IOTSI workshop, we had a discussion about modeling/schema
languages and the opportunities for conversion in order to create
semantic interoperability.

In CoRE, we are having this discussion about device management right
now, and one interesting question is whether the little XML DSL that OMA
LWM2M has here is a candidate for automatic conversion to another
management modeling language, e.g., YANG.

Anybody up to hacking together a prototype?  See
https://www.iab.org/wp-content/IAB-uploads/2016/03/Noise-in-specifications-hurts.pdf
for an example of such a conversion prototype.

Grüße, Carsten

These are pretty bold statements. Claiming something is simple and
knowing something is simple are sometimes different things. Have you
worked throught the details? Is there a decent public definition of
the 'simpler (subset) modeling language'? And with public I mean
public, not hidden behind all sorts of registration walls.
