Currently RDFShape can be used to validate RDF data in general, as well as an Wikidata items through wikidata's endpoint.

However, the validation of wikidata items can be improved in several ways:

• Visualizing the labels of items and properties in the shapes
• Visualizing the labels of items and properties in the error messages
• Adding syntax highlighting to the ShEx editor with auto-complete features similar to those from wikidata query service
• Allowing to have the same set of predefined prefix declarations as in the wikidata query service so people who are familiar with wdqs can also validate items easily
• Adding several options specific to wikidata to the menu to guide the use cases of that community

In this way, the usability of the validation tool could greatly improve for wikidata users.
