use WebService::Kramerius::API4;
my $obj = WebService::Kramerius::API4->new(%params);
my $item_json_hr = get_item($item_id)
my $item_children_json_hr = get_item_children($item_id);
my $item_siblings_json_hr = get_item_siblings($item_id);
my $item_streams_json_hr = get_item_streams($item_id);
my $item_stream = get_item_streams_one($item_id, $stream_id);
my $item_image = get_item_image($item_id);
my $item_preview_image = get_item_preview($item_id);
my $thumb_image = get_item_thumb($item_id);
my $foxml_xml_hr = get_item_foxml($item_id);

METHODS

new(%params)

Returns reference to HASH.
get_item_streams_one($item_id, $stream_id)

Returns stream value when particular output dispatch doesn't set.
Otherwise returns value from output dispatch.
