This is not a real glossary (yet), it's just an example.
Most current digital camera store images using Exif compressed files. Exif compressed files use the baseline JPEG DCT format specified in ISO/IEC 10918-1. This means the image data can be read by any application supporting "JPEG", including essentially all web browsers and image editing, desktop presentation, and document creation applications. In addition, Exif/JPEG stores metadata within application segments at the beginning of the file, and uses sRGB as the default color space.
