MARC::Moose::Lint::Checker - A class to 'lint' biblio record based on a rules file
version 1.0.12
Name of the file containing validation rules based on which a biblio record can be validated.
This method checks a biblio record, based on the current 'lint' object. The biblio record is a MARC::Moose::Record object. An array of validation errors/warnings is returned. Those errors are just plain text explanation on the reasons why the record doesn't comply with validation rules.
use MARC::Moose::Record; use MARC::Moose::Reader::File::Iso2709; use MARC::Moose::Lint::Checker; # Read an ISO2709 file, and dump found errors my $reader = MARC::Moose::Reader::File::Iso2709->new( file => 'biblio.mrc' ); my $lint = MARC::Moose::Lint::Checker->new( file => 'unimarc.rules' ); while ( my $record = $reader->read() ) { if ( my @result = $lint->check($record) ) { say "Biblio record #", $record->field('001')->value; say join("\n", @result), "\n"; } }
Validation rules are defined in a textual form. The file is composed of two parts: (1) field rules, (2) validation tables.
(1) Field rules define validation rules for each tag. A blank line separates tags. For example:
102+ # # abc+i@CTRY ^[a-z]{3}$ 2+
Line 1 contains the field tag. If a + is present, the field is repeatable. If a _ is present, the field is mandatory. For control fields (tag under 010), an optional second line can contain a regular expression on which validating field content. For <standard fields>, line 2 and 3 contains a regular expression on which indicators 1 and 2 are validated. # means a blank indicator. Line 4 and the following define rules for validating subfields. A first part contains subfield's letters, and + (repeatable) and/or _ (mandatory), followed by an optional validation table name begining with @. A blank separates the first part from the second part. The second part contains a regular expression on which subfield content is validated.
(2) Validation tables part of the file allow to define several validation tables. The table name begins with ==== TABLE NAME in uppercase. Then each line is a code in the validation table.
==== TABLE NAME
This is for example, a simplified standard UNIMARC validation rules file:
005 \d{14}\.\d 100_ # # a ^[0-9]{8}[a-ku][0-9 ]{8}[abcdeklu ]{3}[a-huyz][01 ][a-z]{3}[a-cy][01|02|03|04|05|06|07|08|09|10|11|50]{2} 101_ 0|1|2 # abcdfghij+@LANG ^[a-z]{3}$ 200_ 0|1 # a_+ bcdefghi+ v z5+ ==== CTRY AF AL DZ GG GN GW GY HT HM VE VN VG VI ZM ZW ==== LANG aar afh afr afa ain aka akk
