Classification and indexing schemes are of considerable interest to me
but I admit to not having any firm answers yet.  The comments by Jan
Kijlstra seem to be right on target for someone looking for information
on a given instrument type.  On the other hand, secondary topics with
this scheme may be difficult to locate.  Thus the need for cross indexing
of some sort.

May I also suggest the addition of an item for music theory as it might
apply to arrangements done for mechanical music?  This could be a
secondary or even tertiary level subject in most cases yet there may be
those musicologists who would want to search the archives of MMD.
