I would have used .json or .xml; the content of the file after all is
self-describing and tools like 'file' might learn how to recognize the
content. Extensions like .yidxml and .yidjson looks a bit horrible to
me and so far I never had any real problems using .json and .xml for
arbitrary json and xml files (and .json and .xml helps generic tools
so calling it .yid means that I have to go and teach tools that .yid
is either .json and .xml). Try loading .json and .xml in your
favourite editor and then load a .yid file. Big difference for my
editor. So from my perspective, do nothing (and then people and tools
will likely use option 3).
