NAME

Datahub::Factory::Importer::EIZ - Import data from the ErfgoedInzicht OAI-PMH endpoint

SYNOPSIS

use Datahub::Factory::Importer::EIZ;
use Data::Dumper qw(Dumper);

my $oai = Datahub::Factory::Importer::EIZ->new(
    url                    => 'https://endpoint.eiz.be/oai',
    metadataPrefix         => 'oai_lido',
    set                    => '2011',
);

$oai->importer->each(sub {
    my $item = shift;
    print Dumper($item);
});

DESCRIPTION

Datahub::Factory::Importer::EIZ imports data from the ErfgoedInzicht OAI-PMH endpoint. By default it uses the ListRecords verb to return all records using the oai_lido format. It is possible to only return records from a single Set or those created, modified or deleted between two dates (from and until).

It automatically deals with resumptionTokens, so client code does not have to implement paging.

PARAMETERS

The endpoint parameter and some PID module parameters are required.

To link PIDs (Persistent Identifiers) to MSK records, it is necessary to use the PID module to fetch a CSV from either a Rackspace Cloud Files (protected by username and password) instance or a public website. Depending on whether you choose Rackspace or a Web site, different options must be set. If an option is not applicable for your selected module, you can skip the parameter or set it to undef.

The CSV files are converted to sqlite tables inside /tmp and can be used in your fixes. See msk.fix for an example.

endpoint

URL of the OAI endpoint.

handler( sub {} | $object | 'NAME' | '+NAME' )

Handler to transform each record from XML DOM (XML::LibXML::Element) into Perl hash.

Handlers can be provided as function reference, an instance of a Perl package that implements 'parse', or by a package NAME. Package names should be prepended by + or prefixed with Catmandu::Importer::OAI::Parser. E.g foobar will create a Catmandu::Importer::OAI::Parser::foobar instance. By default the handler Catmandu::Importer::OAI::Parser::oai_dc is used for metadataPrefix oai_dc, Catmandu::Importer::OAI::Parser::marcxml for marcxml, Catmandu::Importer::OAI::Parser::mods for mods, Catmandu::Importer::OAI::Parser::Lido for Lido and Catmandu::Importer::OAI::Parser::struct for other formats. In addition there is Catmandu::Importer::OAI::Parser::raw to return the XML as it is.

metadata_prefix

Any metadata prefix the endpoint supports. Defaults to oai_lido.

set

Optionally, a set to get records from.

from

Optionally, a must_be_older_than date.

until

Optionally, a must_be_younger_than date.

username
