Re: Blank nodes must DIE! [ was Re: Blank nodes semantics - existential variables?]

Sounds like a task for SHACL, no? Ignore the nonsense about comparing it to OWL: it is a macro language for describing /syntactic/ constraints on RDF graphs. Doesn’t that give you the required atomicity?.

With a triples-based (description of a ) data structure you have to be constantly on your guard that every subset of the full graph pattern is at least sensible and harmless, even when subsetting these chunks is often confusing or misleading for data consumers. I can't help wondering whether notions of graph shapes [ . . . ] could be exploited to create an RDF-based data format which had atomicity at the level of entire shapes.
