Chord Symbol Standards

Is there a standard schema (yet) for chord symbols, whereby any voicing can be expressed alphanumerically and be machine readable? For example, I had an odd chord that I was using the other day, and it wasn't clear how to write it. Would it be written "F-6/9" (as in jazz) or "Fmin6 (add 9)"? 

A standard symbol mask could be: 

pitch_M/m_(extension1)_(extension2)

Examples:

D(2)

D(6,9)

Dm6

Dm(6,9)

D(9)

DM7

DM7(+11)

Dm7

D7(+9)

D7(-9)

D7(+5,+9)

D(-5) Diminished

D(+5) Augmented

Dm7(-5)

D9

D11

D13
