|
|
=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.
