non-repeatable fields with repeatable subfields. |
|
246 |

This is sane for most cases. Something like: |
247 |
|
|
248 |
|
900a-1 900b-1 900c-1 |
249 |
|
900a-2 900b-2 |
250 |
|
900a-3 |
251 |
|
|
252 |
|
will be created from any combination of: |
253 |
|
|
254 |
|
900a-1 900a-2 900a-3 900b-1 900b-2 900c-1 |
255 |
|
|
256 |
|
and following rules: |
257 |
|
|
258 |
B<TODO>: implement exceptions to magic |
marc('900','a', rec('200','a') ); |
259 |
|
marc('900','b', rec('200','b') ); |
260 |
|
marc('900','c', rec('200','c') ); |
261 |
|
|
262 |
|
which might not be what you have in mind. If you need repeatable subfield, |
263 |
|
define it using C<marc_repeatable_subfield> like this: |
264 |
|
|
265 |
|
marc_repeatable_subfield('900','a'); |
266 |
|
marc('900','a', rec('200','a') ); |
267 |
|
marc('900','b', rec('200','b') ); |
268 |
|
marc('900','c', rec('200','c') ); |
269 |
|
|
270 |
|
will create: |
271 |
|
|
272 |
|
900a-1 900a-2 900a-3 900b-1 900c-1 |
273 |
|
900b-2 |
274 |
|
|
275 |

There is also support for returning next or specific using: |
276 |
|
|
277 |
|
while (my $mf = WebPAC::Normalize:_get_marc_fields( fetch_next => 1 ) ) { |
278 |
|
# do something with $mf |
279 |
|
} |
280 |
|
|
281 |
|
will always return fields from next MARC record or |
282 |
|
|
283 |
|
my $mf = WebPAC::Normalize::_get_marc_fields( offset => 42 ); |
284 |
|
|
285 |

will return 42th copy record (if it exists). |

You can think about this lookup as SQL (if that helps): |
1003 |
|
|
1004 |
|
select |
1005 |
|
sub { what } |
1006 |
|
from |
1007 |

database, input |
1008 |

having |
1011 |
