"SHACL validation tools can verify whether your data fulfills the constraints described by your data model, similar to how XML Schema or JSON Schema are being used."
"SHACL is based on RDF and supports the validation of graph-based and object-oriented data. Since SHACL is based on RDF, it may also serve as a schema language for JSON via its JSON-LD dialect"

The suggestion is supported by some web page authors: https://www.topquadrant.com/technology/shacl/tutorial/
