| http://www.w3.org/ns/prov#value | - The Compression Ratio is defined by: Cr = n1/n2 Example: A picture 320x240, 24bit (3 byte, 1 byte per RGB-channel) per pixel can be saved without any compression by 320 x 240 x 3 = 230400 bytes (this is done e.g. if the picture is saved as 'bmp-file' using windows).
