In 2010 the Federal Agencies Digitization Initiative (FADGI) – Still Image Working Group titled published “Technical Guidelines for Digitizing Cultural Heritage Materials: Creation of Raster Image Master Files.” As stated in the guidelines, “some of the primary objectives of these guidelines are to: provide an approach to digitization that is practical today, describe technical parameters that promote a “well-defined” imaging environment, provide a consistent approach to imaging and metadata collection that will be appropriate for a wide range of outputs and purposes, and define a common set of quality or performance metrics to be used in describing and evaluating the digital object, as well as methods of validating those measures to defined requirements.”
