Koha::RecordProcessor - Dispatcher class for record normalization


  use Koha::RecordProcessor;
  my $normalizer = Koha::RecordProcessor(%params);


Dispatcher class for record normalization. RecordProcessors must extend Koha::RecordProcessor::Base, be in the Koha::Filter namespace, and provide the following methods:

filter ($record) - apply the filter and return the result. $record may be either a scalar or an arrayref, and the return result will be the same type.

These methods may be overriden:

initialize (%params) - initialize the filter

destroy () - destroy the filter

These methods should not be overridden unless you are very sure of what you are doing:

new () - create a new filter object

Note that the RecordProcessor will not clone the record that is passed in. If you do not want to change the original MARC::Record object (or whatever type of object you are passing in), you must clone it prior to passing it off to the RecordProcessor.



    my $normalizer = Koha::RecordProcessor->new(%params);

Create a new normalizer. Available parameters are:


Which metadata schema is in use. At the moment the only supported schema is 'MARC'.


What filter(s) to use. This must be an arrayref to a list of filters. Filters can be specified either with a complete class path, or, if they are in the Koha::Filter::${schema} namespace, as only the filter name, and "Koha::Filter::${schema}" will be prepended to it before the filter is loaded.



Bind a normalizer to a particular record.


    my $newrecord = $normalizer->process([$record])

Run the record(s) through the normalization pipeline. If $record is not specified, process the record the normalizer is bound to. Note that $record may be either a scalar or an arrayref, and the return value will be of the same type.


    my @available_filters = Koha::RecordProcessor::AvailableFilters([$schema]);

Get a list of available filters. Optionally specify the metadata schema. At present only MARC is supported as a schema.
