SHACL is a W3C-proposed language for expressing structural constraints on RDF graphs. In recent years, SHACL’s popularity has risen quickly. This rise in comes with questions related to its place the semantic web, particularly about relation OWL (the de facto standard ontological information web) and description logics (which form formal foundations of OWL). We answer these by arguing that fact logic. On one hand, our surprisingly simple, some might even say obvious. But, other also controversial. By resolving this issue once all, we establish field as solid SHACL.
