Back to Changing the Bioghist labels
DemofaFC::GetBioghistTocHead
This is a replacement for the base FindaidClass GetBioghistTocHead which uses the first <head> element in the <bioghist> for the Table of Contents and region labels for the <bioghist> instead of the Bentley practice of relying on the label attribute of the <archdesc> to determine the label for the <bioghist> See $DLXSROOT/cgi/f/findaid/FindaidClass/DemofaFC.pm for the full code.

# Replacement to use <head> within Biohist for label

# NAME : GetBioghistTocHead
# PURPOSE :
# CALLS :
# INPUT :
# RETURNS :
# GLOBALS :
# SIDE-EFFECTS :
# NOTES : The original code in the base class uses a query based on the encoding
# practice of the Bentley Historical Library at the University of
# Michigan. Though the distinction between
# "collections" (papers of indiviudals) and "records" or "record group"
# (records of organizations) is an archival distinction, the use of the
# archdesc attribute to determine the label is probably a BHL idiosyncracy.
# Our practice goes back to early discussions that whenever possible the
# system / stylesheet should supply standard headings.
# Most libraries probably hard code a <head>, in which case it would be necessary to
# overide this method in as is done in the example subclass below.
