[three hours later] O … K … Skip ahead if you don't want to read me ranting.
If you want something that's *way* overspecified (I do not want to implement a
structured version of SQL queries – among other interesting things – nor do I
see any need to do so) and impossible to implement without (a) access to the
reference implementation and its test cases and (b) at least a man year for
the basics (the Java server example is 430 lines -- more than 70(!) import
statements, way too few comments, and a heap of empty handlers most people
would find to be somewhat essential), be my guest.
This eerily reminds me of the X.400 train wreck of the 1980s.
In any case, this is the OWFS list. I can guarantee that nobody in their right
mind would ever connect an 1820 temperature sensor to such a system.

They also want $3000 for access to their C source code. Redistribution is not
permitted, sorry, so any open source implementation will have to be done from
scratch.

Look at how much FHEM or OpenHAB can do. Ultimately I would like to build [the
foundation of] something that's as capable, but somewhat more reliable (no
single point of failure) and accessible ("if X, do Y" should be three lines of
debuggable Python/Perl/whatever, or three Node:Red clicks).
In any case I am no re-inventing any wheels. The wheels are out there, I can
learn how they're built, and decide to use them in a vehicle that is easier to
driver than what's already out there and that'll stay on track if one of the
wheels gets loose.

Adding commercials to emails is not a particularly good idea IMHO.
