What Is an XMP File and How Is It Used in Photography?

In photography, specifically in post-processing and editing, XMP Data is the data standard for Adobe’s Extensible Metadata Platform. In XMP enabled applications photographers and editors are able to embed metadata directly into popular image file formats such as JPEG files. Using XMP means that so-called ‘sidecar’ metadata files are no longer required, vastly simplifying the file organization and storage workflow for photographers. Files containing XMP data are still able to be opened and edited in applications that do not support XMP data, the metadata contained within the file however is only editable within XMP compatible applications such as Adobe’s photoshop suite.
