Thanks, Holger. My need in this case isn't to query inferred data using SPARQL or GraphQL, but rather to reuse the inferred data as an input for another EDG property shape with another sh:values rule in it. I think I'm hearing that that's not possible.
Can you point me to where I can read more about the materialization option and decide whether there's a way to make that work for this use case? Thanks.
