IRI match pattern in SHACL

[Simon Cox]

Is it possible in SHACL to test if an IRI matches a pattern (e.g. contains a substring). `sh:pattern` is restricted to string-literals. In SPARQL you can cast an IRI to a string to manipulate or match it. Is there a native way in SHACL to do this?

sh:pattern should work. See https://www.w3.org/TR/shacl/#PatternConstraintComponent it uses the equivalent of the str(?valueNode) function so it will convert URI nodes to strings before applying the regex.
