Example node

This node comes from .robos/kgraphs/learning/package.jsonld in the RobOS repository. That graph holds sample data for a fictional company, so treat the values as illustrations.

{
  "@id": "urn:robos:credential:certificate:course-test-architect-mucvneo3",

Validate the example

Save the example as node.json in the repository root, then run:

node -e "const { SHACLValidator } = require('./packages/robos-graph/lib/shacl-validator'); console.log(new SHACLValidator().validate([require('./node.json')]).conforms)"

The command prints true when the node meets every rule for its types.
