This is my thought, yes. I was thinking something along the lines of

Jim,
I like your idea.
I think your example needs to be more like:
create the filename temperature
read a 16 bit int at address x
push it through transform table q that outputs a float
output the float with the printf string %s.
This assumes that the transform is done on the OWFS side rather
To answer a very small part of your question: No problem. The owserver that
actually connects to the slave in question will be the one that holds its
configuration.
It seems like you almost want a small transform language embedded in OWFS.
Does this already exist? It would be nice to use an
Paul,
I wasn't so much thinking about what was right but looking at
generalizing what OWFS does today.
How do you convert from the data reading on a 18B20 to a temperature?
Same goes for a humidity level or a thermocouple reading.
It seems like you have readings you get back, and by knowing
Yes, I was intending on this being stored in eeprom on the slave
device. I believe in most cases, the slave device will be soldered on
a board with its support electronics for whatever task it is doing.
As such, its task is not going to change.
I am NOT (currently) proposing that information
So if I understand correctly, the firmware upload not only programs the
slave, it also contains information for OWFS to parse and create the
devices?

Jim,
Is this going into EEPROM? I was thinking you were saying this happened
each time the slave came up.

You are closer to my view of control systems. I generally want
susbsystems to be able to act autonomously with the brains doing the
more complex work. So it's more like a hierarchy than a pure mesh. I
also think about redundancy. Just because 1wire is low cost doesn't mean
it can't be
