+Semantic shapes enables you to validate RDF graphs against a set of conditions. Semantic shapes can also be viewed as a description of the data graphs that do satisfy these conditions. Such descriptions may be used for a variety of purposes beside validation, including user interface building, code generation and data integration. Semantic shapes could be described in SHACL or ShEx languages.
