NAME
Wikibase::Datatype::Struct::Item - Wikibase item structure serialization.
SYNOPSIS
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::Item 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 item to object.
Returns Wikibase::Datatype::Item instance.
ERRORS
obj2struct():
Base URI is required.
Object doesn't exist.
Object isn
't '
Wikibase::Datatype::Item'.
struct2obj():
Structure isn
't for '
item' type.
