The Extensible Metadata Platform (XMP) is a metadata standard used to store metadata about photos and their processing steps. With XMP, various data can be stored in a uniform format. XMP has no fixed data fields
, but consists of various substandards. It was developed by Adobe Systems and is supported by many Adobe products. XMP defines in which form the metadata, i.
e. information about the photo and its processing, is embedded in the files. The data can be embedded in the image files or stored separately. Through the metadata, each individual processing step of a photograph is documented and can be reproduced at any time. For a photograph, the metadata may be the title and photographer, whether the photograph was taken or scanned, how it was processed and edited, and in what form the photograph was output; whether via printer, imagesetter or screen. Each program and hardware component involved in the process
adds its own information to the metadata, so that the final product file contains all the information about the photo and its individual processing steps.syntax
