C4::AuthoritiesMarc::MARC21
=head1 SYNOPSIS
use C4::AuthoritiesMarc::MARC21;
=head1 DESCRIPTION
This is a helper module providing functions used by
C<C4::AuthoritiesMarc> to deal with behavior specific
to MARC21 authority records (as opposed to other
MARC formats).
Functions from this module generally should not be used
directly; instead, use the appropriate function from
C<C4::Authorities> that will dispatch the appropriate
function based on the marcflavour system preference.
=head1 FUNCTIONS
=cut
=head2 get_heading_type_from_marc
my $auth_type = get_auth_type_from_marc($marc);
Given a MARC::Record object containing an authority record,
determine its heading type (e.g., personal name, topical term,
etc.).
=cut
=head2 default_auth_type_location
my ($tag, $subfield) = default_auth_type_location();
Get the tag and subfield used to store the heading type
if not specified in the MARC framework. For MARC21,
this defaults to 942$a.
=cut
sub default_auth_type_location {
return ('942', 'a');
}
=head2 fix_marc21_auth_type_location
fix_marc21_auth_type_location($auth_marc, $auth_type_tag, $auth_type_subfield);
If the incoming C<MARC::Record> object has a 152$b, remove it. If no
field already exists that contains the specified C<$auth_type_tag>
and C<$auth_type_subfield>, create a new field whose contents
are the original contents of the 152$b.
This routine exists to deal with a historical problem: MARC21
authority records in previous versions of Koha kept the
authority type in the 152$b. While the 152 may be OK for UNIMARC,
a 9XX should have been used for MARC21.
This function is meant to be called from GetAuthority, GetAuthorityXML,
and AddAuthority.
FIXME: This function should be removed once it's determined
that no MARC21 users of Koha are using the 152$b
to store the authority type.
=cut
sub fix_marc21_auth_type_location {
my ($auth_marc, $auth_type_tag, $auth_type_subfield) = @_;
my $auth_type_code;
return unless $auth_type_code = $auth_marc->subfield('152', 'b');
$auth_marc->delete_field($auth_marc->field('152'));
unless ($auth_marc->field($auth_type_tag) && $auth_marc->subfield($auth_type_tag, $auth_type_subfield)) {
$auth_marc->add_fields($auth_type_tag,'','', $auth_type_subfield=>$auth_type_code);
}
