But those are protocols and not data models like SMIv2 or Yang.
E.g., IPFIX can *carry* structured information like SMIv2.

AFAIK IETF only has those two languages for data models.

It took the IETF order of 20 years to go from SMIv2 to Yang, and I sure 
hope 6lo is done before a third data model language is introduced in the 
IETF.
