SHACL and ShEx can express those kinds of constraints, so they are a 
step forward, but they are not integrated into an RDF language.  A 
higher-level RDF-ish language should have this ability built into the 
language-- to express and manipulate chunks of data integrated -- just 
as it is in any modern programming language.
