If you already have the validate tool installed elsewhere, update the below path to it.
npm install --save shex
./node_modules/shex/bin/validate -d aop.ttl -x ker.shex -n http://identifiers.org/aop.relationships/597The Jupyter notebook also contains the same ShEx example, for both a local .ttl file and through a SPARQL query against a public SPARQL endpoint.
