=head1 SYNOPSIS |
51 |
|
|
|
52 |
dpavlin |
536 |
This module uses C<conf/normalize/*.pl> files to perform normalisation |
53 |
|
|
from input records using perl functions which are specialized for set |
54 |
|
|
processing. |
55 |
dpavlin |
10 |
|
56 |
dpavlin |
536 |
Sets are implemented as arrays, and normalisation file is valid perl, which |
57 |
|
|
means that you check it's validity before running WebPAC using |
58 |
|
|
C<perl -c normalize.pl>. |
59 |
dpavlin |
15 |
|
60 |
dpavlin |
536 |
Normalisation can generate multiple output normalized data. For now, supported output |
61 |
dpavlin |
540 |
types (on the left side of definition) are: C<tag>, C<display>, C<search> and |
62 |
dpavlin |
547 |
C<marc>. |

=head1 FUNCTIONS |
65 |
|
|
|
66 |
dpavlin |
538 |
Functions which start with C<_> are private and used by WebPAC internally. |
67 |
|
|
All other functions are available for use within normalisation rules. |
68 |
|

707 |
Options C<row>, C<rules> and C<log> are mandatory while all |
86 |
dpavlin |
540 |
other are optional. |
87 |
|
|
|
88 |
dpavlin |
736 |
C<load_row_coderef> is closure only used when executing lookups, so they will |
89 |
dpavlin |
725 |
die if it's not defined. |
90 |
|
|
|
91 |
dpavlin |
536 |
This function will B<die> if normalizastion can't be evaled. |
92 |
dpavlin |
15 |
|
93 |
dpavlin |
538 |
Since this function isn't exported you have to call it with |
94 |

C<WebPAC::Normalize::data_structure>. |

We are using I<magic> which detect repeatable fields only from |
243 |
|
|
sequence of field/subfield data generated by normalization. |
244 |
|
|
|
245 |
dpavlin |
554 |
Repeatable field is created when there is second occurence of same subfield or |
246 |
|
|
if any of indicators are different. |
247 |
dpavlin |
543 |
|
248 |
dpavlin |
554 |
This is sane for most cases. Something like: |
249 |
dpavlin |
543 |
|
250 |
dpavlin |
554 |
900a-1 900b-1 900c-1 |
251 |
|
|
900a-2 900b-2 |
252 |
|
|
900a-3 |
253 |
|
|
|
254 |
|
|
will be created from any combination of: |
255 |
|
|
|
256 |
|
|
900a-1 900a-2 900a-3 900b-1 900b-2 900c-1 |
257 |
|
|
|
258 |
|
|
and following rules: |
259 |
|
|
|
260 |
|
|
marc('900','a', rec('200','a') ); |
261 |
|
|
marc('900','b', rec('200','b') ); |
262 |
|
|
marc('900','c', rec('200','c') ); |
263 |
|
|
|
264 |
|
|
which might not be what you have in mind. If you need repeatable subfield, |
265 |
|
|
define it using C<marc_repeatable_subfield> like this: |
266 |
|
|
|
267 |
dpavlin |
574 |
marc_repeatable_subfield('900','a'); |
268 |
|
|
marc('900','a', rec('200','a') ); |
269 |
|
|
marc('900','b', rec('200','b') ); |
270 |
|
|
marc('900','c', rec('200','c') ); |
271 |
dpavlin |
554 |
|
272 |
dpavlin |
574 |
will create: |
273 |
|
|
|
274 |
|
|
900a-1 900a-2 900a-3 900b-1 900c-1 |
275 |
|
|
900b-2 |
276 |
|
|
|
277 |
|
|
There is also support for returning next or specific using: |
278 |
|
|
|
279 |
|
|
while (my $mf = WebPAC::Normalize:_get_marc_fields( fetch_next => 1 ) ) { |
280 |
|
|
# do something with $mf |
281 |
|
|
} |
282 |
|
|
|
283 |
|
|
will always return fields from next MARC record or |
284 |
|
|
|
285 |
|
|
my $mf = WebPAC::Normalize::_get_marc_fields( offset => 42 ); |
286 |
|
|
|
287 |
|
|
will return 42th copy record (if it exists). |

1023 |

select |

sub { what } |
1025 |
