    • allow to programmatically access different configuration variables of a Wikibase instance to make it easier for tools to built on top of it
    • investigate ranking for Items to order them by their relevance in a query result
    • com up with a workflows for editing statements linking to other Items in the Wikidata Bridge
    • identify how to improve Wikidata's accessibility
    • create design system components to continue improving consistency
