Naming Schema for Hansen's Sno-Bliz Digitized Files

Basic naming schema

sb_xx9999_x.ext

sb = this is the code for all files to keep the set together.
xx = Two letter code to represent the original source*
9999 = number in which item was scanned. Numbering system is reset for each major type of item
x = type of digital file (preservation, access, derivative)**

*Working list of Two Letter Codes after preliminary assessment:

CodeResource Type
arNewspaper/Magazine Article
auAudio Recording
cg Collage of Photographs (scanned as one item)
cpCup Image (Opaque or Transparency)
doPaper documents (such as business cards and letters)
dp Digital photograph (photograph was born digital)
phPhotograph
sgSigns
vd Video Recording (either digitized or born digital)

**Types of digital files

A minimum of three digital files will be created for each digitized item. The raw totally unedited file is considered the preservation file and will have a 'p' at the end of the file name. A raw slightly edited (eg., color corrected, color bars removed, straightened) version of the file is considered the access file and will have an 'a' at the end of the file name. Any further modifications to the file (eg., shrinking, change of ppi, change of size, change of file type) is considered a derivative file and will have a 'd' at the end of the file.

If an item has to be scanned in parts, then there will be a letter after each part of the preservation file. The access file should be one complete file of the full stitched together image.

If there are multiple versions of a derivative file, each version will have a letter after the code, da, db, etc. The collage of photographs, the intent is to place the whole image and then detailed images of each photo online. For this purpose, each single photo section will have a two digit number after the letter d, d01, d02, d03, etc. Numbers will move from top-to-bottom and left-to-right across the collage.
