I just released a new version (0.8) of the Wikidata Toolkit [1]. Wikidata Toolkit is a Java library allowing to easily reuse Wikidata content using dumps or the API but also providing helpers for editing.
This release mainly adds several
fixes that are needed to keep Wikidata Toolkit working with the changes
done on Wikidata provides support for JDK 9.
It also provides two features related to the Wikibase API: it is now
possible to edit labels, descriptions and aliases using the
WikibaseDataEditor (this is a work in progress that is likely to change)
and there is now a wrapper for the wbEntitySearch API action.
