(1) (EXtensible Metadata Platform) An ISO standard for storing and exchanging descriptive data (metadata) about some object. Initially developed by Adobe, XMP data can be embedded into various media formats, including images and PDF files, or it can reside in separate files. In a post-production workflow, the XMP data can be updated as the content passes from one step to the next. See metadata.
