=head1 SYNOPSIS |
=head1 SYNOPSIS |
| 35 |
|
|
| 36 |
This package contains code that could be helpful in implementing different |
This module uses C<conf/normalize/*.pl> files to perform normalisation |
| 37 |
normalisation front-ends. |
from input records using perl functions which are specialized for set |
| 38 |
|
processing. |
| 39 |
|
|
| 40 |
|
Sets are implemented as arrays, and normalisation file is valid perl, which |
| 41 |
|
means that you check it's validity before running WebPAC using |
| 42 |
|
C<perl -c normalize.pl>. |
| 43 |
|
|
| 44 |
|
Normalisation can generate multiple output normalized data. For now, supported output |
| 45 |
|
types (on the left side of definition) are: C<tag>, C<display>, C<search> and |
| 46 |
|
C<marc>. |
| 47 |
|

=head1 FUNCTIONS |
=head1 FUNCTIONS |
| 49 |
|
|
| 50 |
=head2 new |
Functions which start with C<_> are private and used by WebPAC internally. |
| 51 |
|
All other functions are available for use within normalisation rules. |
| 52 |
|
|
| 53 |
|
=head2 data_structure |
| 54 |
|
|
| 55 |
Create new normalisation object |
Return data structure |
| 56 |
|
|
| 57 |
my $n = new WebPAC::Normalize::Something( |
my $ds = WebPAC::Normalize::data_structure( |
| 58 |
cache_data_structure => './cache/ds/', |
lookup => $lookup->lookup_hash, |
| 59 |
lookup_regex => $lookup->regex, |
row => $row, |
| 60 |
|
rules => $normalize_pl_config, |
| 61 |
|
marc_encoding => 'utf-8', |
| 62 |
); |
); |
| 63 |
|
|
| 64 |
Optional parameter C<cache_data_structure> defines path to directory |
Options C<lookup>, C<row>, C<rules> and C<log> are mandatory while all |
| 65 |
in which cache file for C<data_structure> call will be created. |
other are optional. |
| 66 |
|
|
| 67 |
|
This function will B<die> if normalizastion can't be evaled. |
| 68 |
|
|
| 69 |
Recommended parametar C<lookup_regex> is used to enable parsing of lookups |
Since this function isn't exported you have to call it with |
| 70 |
in structures. |
C<WebPAC::Normalize::data_structure>. |
