The coding looks good, and sensible.

How about we just make it a text string, rather than integer. Much clearer to read, and almost no impact on size.

VV.C.P

VV the normal vehicle types, or '*' for generic.

C your class

P your property

• type (integer type code)

For general purpose type codes, maybe some classification scheme would make sense? Maybe adopt some standard scheme already defined for automotive data? ...if there is one...

It seems there is none suitable, so here's my attempt at defining one. Please comment.

Regards,
Michael


Type classification scheme:
    id size: 32 bit integer

Generic / standard props:

    0x 0000 C PPP

Vehicle specific props:

    0x VVVV C PPP

    VVVV = Vehicle ID
        0001 = Tesla Roadster
        0002 = Tesla Model S
        0003 = GM Volt / Opel Ampera
        0004 = Renault Twizy
        ...

C = Class:

...main classes:
   
    0 = Power               
    1 = Engine               
    2 = Transmission       
    3 = Chassis               
    4 = Body               
    5 = Electrics           
   
...auxiliary classes?
   
    6 = Safety                (Chassis, Body, Electrics)
    7 = Security            (Power?, Body, Electrics)
    8 = Comfort                (Chassis, Body, Electrics)
    9 = Entertainment        (Body, Electrics)
    a = Communication        (Body, Electrics)
   
   
    b = reserved
    c = reserved
    d = reserved
    e = reserved
    f = reserved
   

PPP = Property
    ...allowing for 4096 properties per class.
