NAME
Catmandu::Fix::marc_decode_dollar_subfields - decode double encoded dollar subfields
SYNOPSIS
marc_decode_dollar_subfields()DESCRIPTION
In some environments MARC subfields can contain data values that can be interpreted as subfields itself. E.g. when the 245-$a subfield contains the data:
My Title $h subsubfieldthen the $h = subsubfield will not be accessible with normal MARC processing tools. Use the 'marc_decode_dollar_subfields()' fix to re-evaluate all the MARC subfields for these hidden data.
METHODS
marc_decode_dollar_subfields()
Decode double encoded dollar subfields into real MARC subfields.
INLINE
This Fix can be used inline in a Perl script:
use Catmandu::Fix::marc_decode_dollar_subfields as => 'marc_decode_dollar_subfields';
my $data = { record => [...] };
$data = marc_decode_dollar_subfields($data);
