Linked.Archi Core Visual Notation SHACL Shapes

SHACL Shapes

https://meta.linked.archi/core-vis-shapes# ⧉

SHACL shapes for the Linked.Archi diagram and visual notation layer (core-vis). Constrains the diagram interchange classes — ArchNode, LabelNode, ContainerNode, Link, Point, PointList — and the type-level notation classes NotationSet, VisualNotation and Style. Until 0.1.0 the diagram layer had no shapes at all: a validate run loaded the notation's own shapes and the core shapes, none of which target a core-vis class, so nothing checked that a diagram node referenced a model element, that it belonged to a view, or that an edge had endpoints. A corpus of 447 malformed diagram resources across 20 diagrams validated clean. The two load-bearing rules here are ArchNodeShape (a diagram node that claims to stand for a model element must say which one) and PlacedDiagElementShape (a shape or edge must belong to exactly one view); the remainder is cardinality and datatype hygiene.
