Preliminary DTD for Open JPEG "mj2_to_metadata" function.
Last revised: April 20, 2005
Author: Glenn Pearson, at U.S. National Library of Medicine.
See mj2_to_metadata.c regarding copyright, license, disclaimer status.
While the vocabulary of this DTD is based on the relevant portions of the
ISO/IEC JPEG 200 standard, the detailed representation is the author's own.
It is neither an ISO/IEC nor NLM official or consensus representation.
Furthermore, it deviates from a pure representation of the ISO/IEC standard
in these aspects:
- it is incomplete in a number of ways (which to some extent may be
addressed over time);
- it has extensions for "derived" data and "statistics";
- it is more flexible. That is, some elements are marked as optional
not because they are optional in an MJ2 file, but because reporting
of them is optional based on current or projected mj2_to_metadata
command-line flags.
