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 Extension Specification Version 1.2 standard

Note: Exiv2 uses iptcExt (rather than Iptc4xmpExt) as the group name for keys of IPTC Extension schema properties.
