I got the source files updated last night but not all of the .zip files (too big for home bandwidth) so the .json files in some are out of date.  Am planning to refresh them later this morning.

Interesting, good idea.  Haven't done that before but will look at it and try to automate.  Found some documentation:

I don’t know if some of these files do not need to be validated, but since they have a .json extension, they would pass a simple JSON parse test.  One of us has to "go back... to the drawing board.

Looking at individual files first will give you current examples... the first three email attachments are a good start.  All of the direct .json links in the online examples are also current.  For those attached examples, here are the publication links with up-to-date versions:




Each of these passes validation at

At this stage of review, statistics aren't much help since it is the basic pattern we are trying to examine and reconcile.  Any changes we make will ripple through quickly.

None of the files get checked into subversion.  I only check in the .x3d source, not the derived translations.
