    abstract = {Data quality is an important factor for the success of the envisaged
 Semantic Web. As machines are inherently intolerant at the interpretation of
 unexpected input, low quality data produces low quality results. Recently,
 constraint languages such as SHACL were proposed to assess the quality of data
 graphs, decoupled from the use case and the implementation. However, these
 constraint languages were designed with machine-processability in mind.
 Defining data shapes requires knowledge of the language's syntax - usually
 RDF - and specification, which is not straightforward for domain experts, as they
 are not Semantic Web specialists. The notion of constraint languages is very
 recent: the W3C Recommendation for SHACL was finalized in 2017. Thus, user
 interfaces that enable domain experts to intuitively define such data shapes are
 not thoroughly investigated yet. In this paper, we present a non-exhaustive list of
 desired features to be supported by a user interface for editing data shapes. These
 features are applied to unSHACLed: a prototype interface with SHACL as its
 underlying constraint language. For specifying the features, we aligned existing
 work of ontology editing and linked data generation rule editing with data shape
 editing, and applied them using a drag-and-drop interface that combines data
 graph and data shape editing. This work can thus serve as a starting point for data
 shape editing interfaces.
