  dcterms:description "Joint Photographic Experts Group (JPEG) Raw Stream is a JPEG encoding bitstream sequence for images. Raw is defined as an uncompressed image data that is normally proprietary from the specific camera model the image or footage came from. In 1992, when C-Cube Microsystems published the specification for JFIF (JPEG File Interchange Format), JFIF encapsulated the JPEG bitstream. Those JPEG bitstreams can be transmitted or exchanged as Raw and JPEG files can contain the Raw JPEG bitstream within it. In this instance, JPEG/JFIF acts as a wrapper and Raw is the internal bitstream. Since the wrapper JFIF/JPEG is a fully disclosed open standard and widely adopted in the community, the files should be retained as-is." ;
