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.
