As the [PHP implementation of the DataModel](https://github.com/wmde/WikibaseDataModel), this library only implements the basic Item and Property entity types, and the components they are made of. Wikibase uses this library together with the [Wikibase Serialization JavaScript library](https://github.com/wmde/WikibaseSerializationJavaScript)to deserialize API responses from serialized JSON to actual DataModel objects. These objects can then be consumed and manipulated via convenient getter and setter methods, turned back into JSON via the corresponding serializer, and send back to the API.
