 Semantic shapes enable you to validate RDF graphs against a set of conditions.
 Semantic shapes can also be viewed as a description of data graphs that 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.
