Exif
Exchangeable image file format (Exif) is the most popular metadata format used in digital photography. It provides a way of embedding a fixed vocabulary of metadata properties in many file formats, such as JPEG, TIFF, RIFF, and WAV. Exif stores metadata as pairs of a metadata name and a metadata value. These metadata name-value-pairs are also called tags, not to be confused with the tagging in Experience Manager. Modern digital cameras create Exif metadata and modern graphics software support it. Exif format is the lowest common denominator for metadata management especially for images.
A major limitation of Exif is that a few popular image file formats such as BMP, GIF, or PNG do not support it.
Metadata fields defined by Exif are typically technical in nature and are of limited use for descriptive metadata management. For this reason, Experience Manager Assets offers mapping of Exif properties into common metadata schemata and into XMP.
