655 |
|
|
656 |
|
We are using I<magic> which detect repeatable fields only from |
657 |
|
sequence of field/subfield data generated by normalization. |
658 |
|
|
659 |
|
This magic is disabled for all records created with C<marc_template>. |
660 |
|
|
661 |
|
Repeatable field is created when there is second occurence of same subfield or |
662 |
|
if any of indicators are different. |
663 |
|
|
664 |
|
This is sane for most cases. Something like: |
665 |
|
|
666 |
|
900a-1 900b-1 900c-1 |
667 |
|
900a-2 900b-2 |
668 |
|
900a-3 |
669 |
|
|
670 |
|
will be created from any combination of: |
671 |
|
|
672 |
|
900a-1 900a-2 900a-3 900b-1 900b-2 900c-1 |
673 |
|
|
674 |
|
and following rules: |
675 |
|
|
676 |
|
marc('900','a', rec('200','a') ); |
677 |
|
marc('900','b', rec('200','b') ); |
678 |
|
marc('900','c', rec('200','c') ); |
679 |
|
|
680 |
|
which might not be what you have in mind. If you need repeatable subfield, |
681 |
|
define it using C<marc_repeatable_subfield> like this: |
682 |
|
|
683 |
|
marc_repeatable_subfield('900','a'); |
684 |
|
marc('900','a', rec('200','a') ); |
685 |
|
marc('900','b', rec('200','b') ); |
686 |
|
marc('900','c', rec('200','c') ); |
687 |
|
|
688 |
|
will create: |
689 |
|
|
690 |
|
900a-1 900a-2 900a-3 900b-1 900c-1 |
691 |
|
900b-2 |
692 |
|
|
693 |
|
There is also support for returning next or specific using: |
694 |
|
|
695 |
|
while (my $mf = WebPAC::Normalize:_get_marc_fields( fetch_next => 1 ) ) { |
696 |
|
# do something with $mf |
697 |
|
} |
698 |
|
|
699 |
|
will always return fields from next MARC record or |
700 |
|
|
701 |
|
my $mf = WebPAC::Normalize::_get_marc_fields( offset => 42 ); |
702 |
|
|
703 |
|
will return 42th copy record (if it exists). |
704 |
