Yes, we used Structured Keywords. The final structure I would like to get is:
COLLECTION        |        Buckminster Fuller papers, 1920-1983, 
FORMAT      |      photographs, color transparencies, 
LOCATION    |    Series 15    |    Box 2    |    Folder 1, 
REPOSITORY   |   Department of Special Collections, Stanford University Libraries, 
TYPE | still image
If I replace "|" with ";", I cannot get the structure I needed. Is there anyway I can have an unique separator for "COLLECTION", "FORMAT", "LOCATION", etc.
