What is XMP?
XMP, an acronym for "eXtensible Metadata Platform", represents an XML-based metadata standard used extensively within PDF documents and mandated by all ISO PDF subset standards. This technology is formally defined by ISO 16684-1:2019, titled "Graphic technology — Extensible metadata platform (XMP) — Part 1: Data model, serialization and core properties.
XMP acts as a robust tool for embedding structured metadata in digital files, encompassing content, creation, and usage information. This enhances searchability, organization, and cross-platform compatibility. Following standards, XMP greatly aids efficient data management and sharing.
