NAME

MARC::Convert::Wikidata::Object::PublicationDate - Bibliographic Wikidata object for publication date defined by MARC record.

SYNOPSIS

use MARC::Convert::Wikidata::Object::PublicationDate;

my $obj = MARC::Convert::Wikidata::Object::PublicationDate->new(%params);
my $copyright = $obj->copyright;
my $date = $obj->date;
my $earliest_date = $obj->earliest_date;
my $end_time = $obj->end_time;
my $latest_date = $obj->latest_date;
my $precision = $obj->precision;
my $sourcing_circumstances = $obj->sourcing_circumstances;
my $start_time = $obj->start_time;

DESCRIPTION

The object for store publication date in book editions in the Czech National Library.

Possible scenarios are:

Precise date

We could use 'date' parameter to store publication date.

Precise decade

We could use 'date' and 'precision' parameters to store publication date with precision (e.g. decade 1910s).

Date between

We could use 'earliest_date' and 'latest_date' parameters to store publication date.

Date defined as period of time

We could use 'start_time' and 'end_time' parameters to store publication date. e.g. For book series which one volume is from 'start_time' and last volume from 'end_time' publication date.

Date which is with some accuracy

We could use 'date' and 'sourcing_circumstances' parameters do define accuracy (e.g. circa).

We could use previous versions with 'copyright' parameter.
