IPTC Extension schema
+
This schema specifies the IPTC Extension XMP properties. The IPTC
+ Extension schema extends and complements the IPTC Core schema by a set
+ of more granular properties and further specialized rights related
+ properties from the PLUS metadata schema.
+
+ - Exiv2 keys are
Xmp.iptcExt.<Property>
+ - The schema namespace URI is
http://iptc.org/std/Iptc4xmpExt/2008-02-29/
+ - The preferred schema namespace prefix is
Iptc4xmpExt
+
+Reference:
IPTC Photo Metadata 2008 standard
+
Note: Exiv2 uses iptcExt
(rather than Iptc4xmpExt
) as the group name for keys of IPTC Extension schema properties.
