What is XMP?

XMP, an acronym for "eXtensible Metadata Platform", is an XML-based metadata standard widely used in PDF documents and required by all ISO PDF subset standards. This technology is formally defined in ISO 16684-1:2019, titled "Graphic technology - Extensible metadata platform (XMP) - Part 1: Data model, serialization and core properties."

XMP is a powerful way to embed structured metadata in digital files, including content, creation, and usage information. This improves searchability, organization, and cross-platform compatibility. By following standards, XMP supports efficient data management and sharing.
