We are currently in the process of creating a standard
schematic symbol creation process.  Part of this process
includes the specification of a package or geometry type.
We outsource our FAB design, so we would like to use
"industry standard" package types for both through-hole
and SMT devices. 

Do such standards, draft standards or guidelines exist?
If so, where can we obtain a copy?

Thanks for any information,
Don Wellnitz - ADAC Labs.
