Technical Guidelines for Digitizing Cultural Heritage Materials: Creation of Raster Image Master Files. FADGI, 2016


The Technical Guidelines for Digitizing Cultural Heritage Materials: Creation of Raster Image Master Files, represents shared best practices followed by the United States Federal Agencies Digitization Guidelines Initiative (FADGI) Still Image Working Group for digitizing cultural heritage materials, a group dedicated to develop common digitization guidelines for still image materials (such as textual content, maps, and photographic prints and negatives) found in cultural heritage institutions. The guide embraces examples developed since 2004 and was inspired on the further National Archives and Records Administration's Technical Guidelines for Digitizing Archival Records for Electronic Access: Creation of Production Master Files - Raster Images (June 2004), but has been revised and updated in several area, reflecting a state of the art of 2015-2016. The latest version consulted is from August 2016.


Its objectives are very comprehensive to daily practical duties, such as:

• 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.

• 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.


The highlights:

• Intention to be informative, not prescriptive, putting the guide on a open perspective of updating and contribution of other experiences.

• Precise topic division from the summary, which facilitates the use of the resource by a non specialized reader.

• Good technical explanation about the main variables evolved on the digitalization, viewed from their main issues not from specific applications.

• Comprehensible (and understandable) tables about features of the origin and desirable outcome, including the popular applications.

• Extensive table of longevity considerations with essential questions to be broad analyzed before run a preservation project based on digitalized imagining.

• Appendix with technical references linked to the Web.


It is aimed for any digitalization protect of still image, such as actions of archival digital preservation.
