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.
