Hi all,

According to the METS schema, the USE attribute is " A tagging attribute to
indicate the intended use of files within this file group (e.g., master,
reference, thumbnails for image files)." I'm using the mets:fileSec to
capture images of a coin within a larger numismatic XML schema.  The @USE is
an unrestricted xs:string, and this example document -
http://fedora.library.northwestern.edu/fedora/get/inu:inu-afrmap-4333843/source-
uses "recto" as a USE for images of a map.  By this same token, is it
semantically acceptable to have "obverse" and "reverse" as a USE?

Example:

fileGrp use="obverse"
  file use="master"
  file use="reference"
  file use="thumbnail"
fileGrp use="reverse"
  file use="master"
  file use="reference"
  file use="thumbnail"

Thanks,
Ethan
