What role should ShEx and SHACL play in NeoWiki? (ShapeLanguages.md)

[JeroenDeDauw]

Discussion venue for docs/planning/ShapeLanguages.md — the ShEx/SHACL position: native Schemas stay the source of truth, shape languages at the RDF boundaries.

Post here; substantive input from other channels (chats, calls, email) gets distilled into this thread with attribution. The doc remains the authoritative, updated statement of where the design stands — this thread is where it gets shaped. Closed when the doc graduates to an ADR.
