SAG and Software Guidelines
BBF has created the SAG (Software Advisory Group) to enable and coordinate its software activities SAG is defining a set of interdependent software guidelines, including processes and tools as needed, that apply to all BBF software deliverables These guidelines will enable and encourage common approaches across BBF Example: YANG data models depend on BBF YANG BCPs, BBF GitHub guidelines etc.
