NAME MARC::Convert::Wikidata - Conversion class between MARC file to Wikibase::Datatype item. SYNOPSIS use MARC::Convert::Wikidata; my $obj = MARC::Convert::Wikidata->new(%params); my $object = $obj->object; my $type = $obj->type; my $wikidata = $obj->wikidata; DESCRIPTION Original intent of this class was conversion from MARC records in National Library of the Czech Republic to Wikidata. The conversion is not simple, this mean that many things are concrete for this concrete national library.

"type" my $type = $obj->type; Process MARC record and detect which record type is. Supported values are: monograph, audiobook and periodical. Returns string. "wikidata" my $wikidata = $obj->wikidata; Process conversion from MARC record to Wikibase::Datatype::Item which is possible to load to Wikidata. Returns Wikibase::Datatype instance. ERRORS new(): From Class::Utils::set_params(): Unknown parameter '%s'. Parameter 'marc_record' is required.
