Introduction
This is the Oracle Multimedia schema for metadata stored in Application
record sets of the IPTC-NAA Information Interchange Model Version 4.
This metadata is often referred to as 'IPTC' tags.
For the JPEG file format, IPTC metadata is parsed from the APP13 marker.
For the TIFF file format, IPTC metadata is parsed from tag 33723.
All tags with string values are decoded using the ISO-8859-1 character
set. The resulting strings may contain characters that are legal in the
character set but are illegal in XML documents. Illegal XML characters
are replaced with the space (0x20) character.

Structure
The schema defines a number of types, both simple and complex,
to represent some of the IPTC tags. The itpcMetadataType is defined
as a sequence of all the supported IPTC tags. This type is used to define
a single global element that can appear in an instance document.
