 Semantic shapes enable 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.
+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.
