ShERML: Mapping Relational Data to RDF

We present ShERML, a tool for facilitating the data exchange from relational data to RDF. The main feature of the tool is a graphical user interface for designing a relational-to-RDF mapping by drawing arrows between schematic representations of the relational schema on the one hand, and a SHACL or ShEx schema on the other hand. The mapping thus constructed can be used directly by the tool for materializing the RDF graph, or be exported as an R2RML mapping.
