This standard defines the syntax of Shape Expression schemas represented in JavaScript Object Notation (JSON), Resource Description Framework (RDF), and plain text. Shape Expressions (ShEx) is a structural schema language for RDF graphs that expresses structural requirements for terms and relationships in a graph. This standard includes formal semantics for validation of RDF knowledge graphs using ShEx. This validation process includes the definition of Shape Maps to associate nodes in RDF graphs with labeled ShEx. A test suite covers all aspects of syntax and validation.
