This is probably too boring for most but my new job has me setting up a numbering system for documentation. The component numbering is outsourced and follows a YYY-ZZZXXXX-VVV where YYY=the company, ZZZ=component type like 300=resistors,etc; XXXX=a number starting at 0001 usually; and VVV=version. Any suggestions about how to approach this or where to look? Appreciate your help.
