=head1 NAME
Koha::Authority - class to encapsulate authority records in Koha
=head1 SYNOPSIS
Object-oriented class that encapsulates authority records in Koha.
=head1 DESCRIPTION
Authority data.
=cut
use strict;
use warnings;
use C4::Context;
use MARC::Record;
use MARC::File::XML;
use C4::Charset;
use Koha::Util::MARC;
use base qw(Koha::MetadataRecord);
__PACKAGE__->mk_accessors(qw( authid authtype ));
=head2 new
my $auth = Koha::Authority->new($record);
Create a new Koha::Authority object based on the provided record.
=cut
sub new {
my $class = shift;
my $record = shift;
my $self = $class->SUPER::new(
{
'record' => $record,
'schema' => lc C4::Context->preference("marcflavour")
}
);
bless $self, $class;
return $self;
}
=head2 get_from_authid
my $auth = Koha::Authority->get_from_authid($authid);
Create the Koha::Authority object associated with the provided authid.
Note that this routine currently retrieves a MARC record because
authorities in Koha are MARC records by definition. This is an
unfortunate but unavoidable fact.
=cut
sub get_from_authid {

my $record=eval {MARC::Record->new_from_xml(StripNonXmlChars($marcxml),'UTF-8',
(C4::Context->preference("marcflavour") eq "UNIMARC"?"UNIMARCAUTH":C4::Context->preference("marcflavour")))};
return if ($@);
$record->encoding('UTF-8');
# NOTE: GuessAuthTypeCode has no business in Koha::Authority, which is an
# object-oriented class. Eventually perhaps there will be utility
# classes in the Koha:: namespace, but there are not at the moment,
# so this shim seems like the best option all-around.

=head2 get_from_breeding

Create the Koha::Authority object associated with the provided authid.
