ExifTool

ExifTool is free software used for reading, writing, and manipulating image, audio and video metadata. It is platform independent and is both a Perl library and command-line application. ExifTool is a popular tool to incorporate into different types of digital workflows and supports many types of metadata including Exif, IPTC, XMP, JFIF, GeoTIFF, ICC Profile, Photoshop IRB, FlashPix, AFCP and ID3, as well as manufacturer-specific metadata of many digital cameras.

ExifTool implements its own open metadata format. It is designed to encapsulate meta information from many sources, in binary or textual form, and bundle it together with any type of file. It can either be a single file, wrapping existing data, or used as a sidecar file, carrying for example Exif or XMP metadata.
