What it does
Checks if metadata streams defined in a PDF conform to the XMP schema.
About XMP metadata streams
There are two metadata locations in a PDF file:
- The info dictionary contains information about the file, such as the
title, the author, the creation date ... and is visible through the file's
Document properties. It's not in XML format.
- The XMP metadata stream also contains information about the file, but
this information is represented as XMP metadata - XMP referring to Adobe's
labeling technology Extensible Metadata Platform. All
information in the info dictionary is also represented in the XMP metadata
stream dictionary, in the form of XMP properties.
Inconsistencies may occur when only one of the metadata locations has been updated.
