ExifTool is a free and open-source software program for reading, writing, and manipulating image, audio, and video metadata. It is platform independent, available as both a Perl library (Image::ExifTool) and command-line application. ExifTool is commonly incorporated 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 the manufacturer-specific metadata formats of many digital cameras.
The image hosting site Flickr uses ExifTool to parse the metadata from uploaded images.[3]
Meta Information Encapsulation
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.
