After many long years,
GeoPDF is
open and an OGC best practice. I would have like to have seen this go down in 2003 when I first wrote the specification. It would have been very different, since it would have been designed for external consumption (too many naught bits hang out in the LGIDict specification, but it had to get done in about a day and a half...), but it should have been open from the get-go, IMO. A
little gruntle for the ranting set, too...
