=head1 SYNOPSIS |
=head1 SYNOPSIS |
| 58 |
|
|
| 59 |
This package contains code that mungle data to produce normalized format. |
This module uses C<conf/normalize/*.pl> files to perform normalisation |
| 60 |
|
from input records using perl functions which are specialized for set |
| 61 |
|
processing. |
| 62 |
|
|
| 63 |
|
Sets are implemented as arrays, and normalisation file is valid perl, which |
| 64 |
|
means that you check it's validity before running WebPAC using |
| 65 |
|
C<perl -c normalize.pl>. |
| 66 |
|
|
| 67 |
|
Normalisation can generate multiple output normalized data. For now, supported output |
| 68 |
|
types (on the left side of definition) are: C<search_display>, C<display>, C<search> and |
| 69 |
|
C<marc>. |
| 70 |
|
|
| 71 |
It contains several assumptions: |
=head1 FUNCTIONS |
| 72 |
|
|
| 73 |
=over |
Functions which start with C<_> are private and used by WebPAC internally. |
| 74 |
|
All other functions are available for use within normalisation rules. |
| 75 |
|
|
| 76 |
=item * |
=head2 data_structure |
| 77 |
|
|
| 78 |
format of fields is defined using C<v123^a> notation for repeatable fields |
Return data structure |
|
or C<s123^a> for single (or first) value, where C<123> is field number and |
|
|
C<a> is subfield. |
|
| 79 |
|
|
| 80 |
=item * |
my $ds = WebPAC::Normalize::data_structure( |
| 81 |
|
lookup => $lookup_hash, |
| 82 |
|

| 83 |

$store->load_row( database => $database, input => $input, id => $mfn ); |
| 89 |
|
}, |
| 90 |
|
); |
| 91 |
|
|
| 92 |
source data records (C<$rec>) have unique identifiers in field C<000> |
Options C<row>, C<rules> and C<log> are mandatory while all |
| 93 |
|
other are optional. |
| 94 |
|
|
| 95 |
=item * |
C<load_row_coderef> is closure only used when executing lookups, so they will |
| 96 |
|
die if it's not defined. |
| 97 |
|
|
| 98 |
optional C<eval{length('v123^a') == 3}> tag at B<beginning of format> will be |
This function will B<die> if normalizastion can't be evaled. |
|
perl code that is evaluated before producing output (value of field will be |
|
|
interpolated before that) |
|
| 99 |
|
|
| 100 |
=item * |
Since this function isn't exported you have to call it with |
| 101 |
|
C<WebPAC::Normalize::data_structure>. |
| 102 |
|
|
| 103 |
optional C<filter{filter_name}> at B<begining of format> will apply perl |
=cut |
|
code defined as code ref on format after field substitution to producing |
|
|
output |
|
| 104 |
|
|
| 105 |
There is one built-in filter called C<regex> which can be use like this: |
my $load_row_coderef; |
| 106 |
|
|
| 107 |
filter{regex(s/foo/bar/)} |
sub data_structure { |
| 108 |
|
my $arg = {@_}; |
| 109 |
|
|
| 110 |
=item * |
die "need row argument" unless ($arg->{row}); |
| 111 |
|
die "need normalisation argument" unless ($arg->{rules}); |
| 112 |
|
|
| 113 |
optional C<lookup{...}> will be then performed. See C<WebPAC::Lookups>. |
_set_lookup( $arg->{lookup} ) if defined($arg->{lookup}); |
| 114 |
|
_set_ds( $arg->{row} ); |
| 115 |
|
_set_config( $arg->{config} ) if defined($arg->{config}); |
| 116 |
|
_clean_ds( %{ $arg } ); |
| 117 |
|
$load_row_coderef = $arg->{load_row_coderef}; |
| 118 |
|
|
| 119 |
|
no strict 'subs'; |
| 120 |
|
no warnings 'redefine'; |
| 121 |
|
eval "$arg->{rules};"; |
| 122 |
|
die "error evaling $arg->{rules}: $@\n" if ($@); |
| 123 |
|
|
| 124 |
=item * |
return _get_ds(); |
| 125 |
|
} |
| 126 |
|
|
| 127 |
at end, optional C<format>s rules are resolved. Format rules are similar to |
=head2 _set_ds |
|
C<sprintf> and can also contain C<lookup{...}> which is performed after |
|
|
values are inserted in format. |
|
| 128 |
|
|
| 129 |
=back |
Set current record hash |
| 130 |
|
|
| 131 |
This also describes order in which transformations are applied (eval, |
_set_ds( $rec ); |
|
filter, lookup, format) which is important to undestand when deciding how to |
|
|
solve your data mungling and normalisation process. |

Parametar C<filter> defines user supplied snippets of perl code which can |
=head2 _set_config |
|
be use with C<filter{...}> notation. |
|
| 151 |
|
|
| 152 |
C<prefix> is used to form filename for database record (to support multiple |
Set current config hash |
|
source files which are joined in one database). |
|
| 153 |
|
|
| 154 |
Recommended parametar C<lookup_regex> is used to enable parsing of lookups |
_set_config( $config ); |
|
in structures. If you pass this parametar, you must also pass C<lookup> |
|
|
which is C<WebPAC::Lookup> object. |
