Exercise 5.1

SHACL Shapes Constraint Language is a language for validating RDF graphs against a set of conditions. These conditions are provided as shapes, which as also an RDF graph.

Starting from the below SHACL shape, add property shapes for the following predicates

  • foaf:familyName (required)
  • foaf:img (required)
  • foaf:mbox (required)
  • foaf:nick (optional)
  • foaf:homepage (optional)

Thus, you ignore organizations for now. Use your solution of exercise 1.1 as input data for the validation.

Tip: try out your SHACL shapes via https://shacl.org/playground/ or https://shacl-playground.zazuko.com/.
