+      <p>
+        SHACL, the Shapes Constraint Language, is a language for describing the structure
+        of RDF graphs.  SHACL introduces the notion of shapes that can specify constraints
+        on the structure of RDF nodes and edges.  graphs.
+      </p>
+      <p>
+        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.
+      </p>
+      <p>
+        SHACL Rules provides inferencing with the generation of new RDF data from a
+        combination of a set of rules and a base data graph. Rules can be expressed as RDF
+        or in the SHACL Rules Language (SRL).
