=head1 SYNOPSIS |
=head1 SYNOPSIS |
61 |
|
|
62 |
This package contains code that mungle data to produce normalized format. |
This module uses C<conf/normalize/*.pl> files to perform normalisation |
63 |
|
from input records using perl functions which are specialized for set |
64 |
|
processing. |
65 |
|
|
66 |
|
Sets are implemented as arrays, and normalisation file is valid perl, which |
67 |
|
means that you check it's validity before running WebPAC using |
68 |
|
C<perl -c normalize.pl>. |
69 |
|
|
70 |
|
Normalisation can generate multiple output normalized data. For now, supported output |
71 |
|
types (on the left side of definition) are: C<search_display>, C<display>, C<search> and |
72 |
|
C<marc>. |
73 |
|
|
74 |
It contains several assumptions: |
=head1 FUNCTIONS |
75 |
|
|
76 |
=over |
Functions which start with C<_> are private and used by WebPAC internally. |
77 |
|
All other functions are available for use within normalisation rules. |
78 |
|
|
79 |
=item * |
=head2 data_structure |
80 |
|
|
81 |
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. |
|
82 |
|
|
83 |
=item * |
my $ds = WebPAC::Normalize::data_structure( |
84 |
|
lookup => $lookup_hash, |
85 |
|
row => $row, |
86 |
|

90 |
|
my ($database,$input,$mfn) = @_; |
91 |
|
$store->load_row( database => $database, input => $input, id => $mfn ); |
92 |
|
}, |
93 |
|
); |
94 |
|
|
95 |
source data records (C<$rec>) have unique identifiers in field C<000> |
Options C<row>, C<rules> and C<log> are mandatory while all |
96 |
|
other are optional. |
97 |
|
|
98 |
=item * |
C<load_row_coderef> is closure only used when executing lookups, so they will |
99 |
|
die if it's not defined. |
100 |
|
|
101 |
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) |
|
102 |
|
|
103 |
=item * |
Since this function isn't exported you have to call it with |
104 |
|
C<WebPAC::Normalize::data_structure>. |
105 |
|
|
106 |
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 |
|
107 |
|
|
108 |
There is one built-in filter called C<regex> which can be use like this: |
my $load_row_coderef; |
109 |
|
|
110 |
filter{regex(s/foo/bar/)} |
sub data_structure { |
111 |
|
my $arg = {@_}; |
112 |
|
|
113 |
=item * |
die "need row argument" unless ($arg->{row}); |
114 |
|
die "need normalisation argument" unless ($arg->{rules}); |
115 |
|
|
116 |
optional C<lookup{...}> will be then performed. See C<WebPAC::Lookups>. |
_set_lookup( $arg->{lookup} ) if defined($arg->{lookup}); |
117 |
|
_set_ds( $arg->{row} ); |
118 |
|
_set_config( $arg->{config} ) if defined($arg->{config}); |
119 |
|
_clean_ds( %{ $arg } ); |
120 |
|
$load_row_coderef = $arg->{load_row_coderef}; |
121 |
|
|
122 |
=item * |
no strict 'subs'; |
123 |
|
no warnings 'redefine'; |
124 |
|
eval "$arg->{rules};"; |
125 |
|
die "error evaling $arg->{rules}: $@\n" if ($@); |
126 |
|
|
127 |
at end, optional C<format>s rules are resolved. Format rules are similar to |
return _get_ds(); |
128 |
C<sprintf> and can also contain C<lookup{...}> which is performed after |
} |
|
values are inserted in format. |
