Ironically, I think we had older versions which used some similar numbers (I think I remember a J version 6, a long time ago, with only a passing relationship to the current J6).
Meanwhile, the current decoupling of J Engine version from J Application version probably needs a little more thought. Personally, I would be tempted to pattern 9!:14 after "uname" (either http://linux.die.net/man/1/uname or http://linux.die.net/man/2/uname), and also link it to the documentation on how to find the application version. That said, it might also be nice if the identification for the J Engine were obviously different from the identification for the J Application. So I think I would vote for changing 9!:14 to report something like: je7.0.2/isi/2014-02-14/12:34 or je7.0.2/src/2016-02-29/12:34 for a version built from updated sources. Basically, though, 9!:14 is mostly for bug reports and perhaps we should not get too formal about its structure?
