				SHACL is represented in RDF and consists of a SHACL Core RDF vocabulary with terms such as <code>sh:minCount</code>
				to express the most frequently needed <a>constraint</a> kinds.
				However, in order to express more complex constraints, the SHACL Core vocabulary is often not sufficient.
				SHACL-SPARQL [[!shacl]] is one extension mechanism for SHACL to express constraints in SPARQL, allowing shape definitions
				to point at executable SPARQL [[sparql11-query]] queries to perform the validation
