And that's why I suggested a Developer's Guide. It would already be of
value as a means of communication between the people on this list
implementing different H5MD libraries for different languages.

I don't believe it is possible to design a solid data model or file
format without implementing it completely. Every single line in a
specification needs to have some demonstrable impact on a reference
implementation. If it doesn't, then it's useless, unclear, impossible
to do, or all of that. Designing a file format without implementing
it is like writing a program without testing it: bugs are guaranteed.

Going through the messages on this list (not *all* of them of course),
I see too much theoretical discussion and not enough feedback from
practice. People argue based on expected problems rather than on real
ones, and discuss unimportant details rather than fundamental
semantics. Could it be that we are all theoreticians?  ;-)
