Oh, and each description should probably be tagged with a source. That way,
when we change the description of some part in LDraw, the cross-reference
database can be updated.

Yep. A better approach may be modeling a set of properties. So a plate with

requiring a hierarchical classification (is that redundant?) system.
This is probably better described by some fuzzy-logic concepts of which I know
