CHAPTER 10: Scripting Access to XMP Metadata XMPScript object reference 288

XMPUtils object

This class provides additional utility functions for the XMP Toolkit, layered upon the functionality of the

XMPMeta object

. It has only static functions, you cannot create an instance.

X Path-composition functions such as composeArrayItemPath(), provide support for composing path

expressions to deeply nested properties, which you can then pass to the accessor functions in

XMPMeta object

, such as getProperty().

X Higher-level functions such as duplicateSubtree() allow you to manipulate the metadata tree in an

XMPMeta object
