I was thinking of starting with some of the IPC-7351 component
category tags and adding in the missing component types.
The categories CAP, RES, IND, DIO, LED, BAT, etc. would work.
To add sub-categories I would add suffixes.

For example a 330pf 1% 50V X7R ceramic cap in an 0805 package could be
CAP_X7R-331U-50V-102T-0805P

A few other caps --- CAP_NPO, CAP_AE (aluminum electrolytic)
Cap arrays --- CAPCAV, CAPCAX, CAPCAF

For ICs maybe IC_AMP, IC_LDO, IC_74LVC138, etc. or for a unique
IC ... IC__<mfg>_<mfg_pn>. I would add some sort of package suffix code

Still a lot of details to work out.
