NAME
Wikibase::Datatype::Struct::Mediainfo - Wikibase mediainfo structure serialization.
SYNOPSIS
use Wikibase::Datatype::Struct::Mediainfo qw(obj2struct struct2obj);
my $struct_hr = obj2struct($obj, $base_uri);
my $obj = struct2obj($struct_hr);DESCRIPTION
This conversion is between objects defined in Wikibase::Datatype and structures serialized via JSON to MediaWiki.
SUBROUTINES
obj2struct
my $struct_hr = obj2struct($obj, $base_uri);Convert Wikibase::Datatype::Mediainfo instance to structure. $base_uri is base URI of Wikibase system (e.g. http://test.wikidata.org/entity/).
Returns reference to hash with structure.
struct2obj
my $obj = struct2obj($struct_hr);Convert structure of mediainfo to object.
Returns Wikibase::Datatype::Mediainfo instance.
ERRORS
obj2struct():
Base URI is required.
Object doesn't exist.
Object isn't 'Wikibase::Datatype::Mediainfo'.
struct2obj():
Structure isn't for 'mediainfo' type.EXAMPLE1
