Severe data quality problems exist in most public healthcare systems and inconsistent data sets often occur. Consistencyconstraints can be used to dene valid and invaliddata. Existing solutions of such constraints like rule systemsare often diffcult to maintain, not human-readable, and ofa bad quality like containing contradictory rules. With In-DaQu we present an approach that allows domain experts toeasily create and maintain consistency constraints using anintroduced domain-specic language. These constraints arebeing stored in an ontology, which allows for an automatedinconsistency detection in the dened rules themselves. Weidentied several scenarios in which consistency constraintscan be interchanged and exchanged between dierent participants.The approach has been successfully evaluated inthe cancer registry of Lower Saxony.
