sdd:NodeCopy as claim

A sdd:Node is a scene instance depicting one world resource as a shape. Its identity is deterministic — skolemized from (diagram, depicted resource) as a dotted-label fragment IRI, so the same resource is a distinct node in every diagram that shows it (spec §3.3). It carries sdd:depicts (the grounded resource), sdd:parent (its authoring/provenance nesting), plus visual tokens such as sdd:shape and aesthetic geometry (sdd:at, sdd:size).Copy as claim

Rendered values inside a node — labels, numbers, any grounded or aesthetic content — are not bare literals but child sdd:Datum instances. A node connects to others only through sdd:Edge stanzas, which own their anchors on the node's boundary rather than the node knowing about its connections.Copy as claim
