SHACL, the Shapes Constraint Language, is a language for describing the structure of RDF graphs. SHACL can be used to define classes and the properties that instances of these classes can have. SHACL may be used for a variety of purposes such as validating, inferencing, modeling domains, generating ontologies to inform other agents, building user interfaces, generating code, and integrating data.
