Too fast... regarding the class definitions, to achieve readability
here as well I would then suggest using a 3 letter abbreviation.
...main classes:
Power PWR
Engine ENG
Transmission TRX
Chassis CHS
Body BDY
Electrics ELC
...auxiliary classes?
Safety SAF (Chassis, Body, Electrics)
Security SEC (Power?, Body, Electrics)
Comfort CMF (Chassis, Body, Electrics)
Entertainment ENT (Body, Electrics)
Communication COM (Body, Electrics)
Also I would prefer "-" as a separator over ".".
For my current application (battery pack + cell data), that would
result in type codes...
RT-PWR-BattPack
RT-PWR-BattCell
...or general form
*-PWR-BattPack
*-PWR-BattCell
Btw: general purpose codes could be written without "*-" prefix as
well? That would be...
PWR-BattPack
PWR-BattCell

Michael

Silly me just assumed you'd prefer integer... I'm using text codes
in my own DB designs whenever possible due to readability.
In other words: of course! :-)
I'll modify my code now accordingly.

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

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.
