Is there a current complete definition of Shape Expressions? It appears that the two current controlling documents are the Shape Expressions (ShEx) Primer, http://shexspec.github.io/primer/, and Semantics of Shape Expressions Schemas, http://shexspec.github.io/semantics/. The former appears non-normative. It mentions data validation as something that Shape Expressions are supposed to be able to do. The latter discusses the syntax of Shape Expressions schemas and the declarative semantics of Shape Expressions schemas. There is no discussion of how validation is controlled in Shape Expressions or even any definition of validation at all. Instead there is a notion of a graph satisfying a Shape Expressions schema but satisfaction of a Shape Expression schema is not mentioned in the primer. How does validation progress in Shape Expressions? peter PS: From the definition of satisfaction and the Certain Global Typing Witness theorem every Shape Expressions schema is satisfied by every RDF graph.
