    rdfs:comment """Maps the OMG DD Diagram Interchange (DI) package.
Source: DI.cmof — defines the abstract diagram element hierarchy:

  Diagram (abstract) → arch:Diagram → arch:View → arch:ModelConcept
  DiagramElement (abstract) → archvis:DiagElement
    ├── Node (abstract) → archvis:Node
    │   ├── Shape (abstract) → archvis:ArchNode — has bounds : dc:Bounds
    │   │   └── LabeledShape (abstract) — has ownedLabel : Label
    │   ├── Plane (abstract) — has planeElement : DiagramElement [0..*]
    │   └── Label (abstract) → archvis:LabelNode — has bounds : dc:Bounds [0..1]
    └── Edge (abstract) → archvis:Link — has waypoint : dc:Point [2..*], source/target
        └── LabeledEdge (abstract) — has ownedLabel : Label
  Style (abstract) → archvis:Style

Property alignments to core-vis:
  di:source / di:target → rdfs:subPropertyOf archvis:source / archvis:target
  di:modelElement aligns with archvis:archElement (shapes) / archvis:archRelationship (edges)

Cross-package references:
  - Shape.bounds, Label.bounds → dc:Bounds (cmof:DataType from DC.cmof)
  - Edge.waypoint → dc:Point (cmof:DataType from DC.cmof)
  - Diagram.name, Diagram.documentation → dc:String (cmof:PrimitiveType)
  - Diagram.resolution → dc:Real (cmof:PrimitiveType)
  - DiagramElement.modelElement → cmof:Element (external, resolved per-package)

All classes in this package are abstract; concrete subclasses are in BPMNDI."""@en ;
