Overview

Represents an XMP metadata stream.

XMP metadata streams may be attached to most PDF objects, though it only makes sense for some of them.

There is also a main XMP metadata stream for the whole document that is accessible via the /Metadata key of the document catalog. That metadata stream should contain the same values as the PDF’s info dictionary and may contain additional entries. This can be accomplished via HexaPDF::Document#metadata.

See: PDF2.0 s14.3.2
