Systems and methods are provided for multi-language support through the management of multi-valued attributes. A data store maintains multi-valued attributes having language components and value components. The value components specify language specific values for the attributes and can be associated with corresponding language components. A server in communication with the data store can provide outputs to requesting users in accordance with a preferred language. For example, a request to access an identity profile maintained by an Identity System can be fulfilled by constructing a page or other output including the requested profile data. An Identity Server can construct the output to include attribute values corresponding to the preferred language associated with the request. Attribute configuration data can similarly be maintained with language components and value components. The configuration of an attribute such as its display name can be included in an output in accordance with a preferred language.
