• Model class. Distinguish between left and right
  references
• class DBModel extends WModel
• reference leftModel container ModelRefXMILeft
• reference rightModel container ModelRefXMIRight
• Model references. To keep track of woven models
• abstract class ModelRefXMI extends WModelRef
• attribute type String
• reference ownedElementRef0- container
  ElementRefXMI oppositeOf modelRef
• class ModelRefXMILeft extends ModelRefXMI
• class ModelRefXMIRight extends ModelRefXMI
• References to each woven element
• class ElementRefXMI extends WElementRef
• reference modelRef WModelRef oppositeOf
  ownedElementRef

• Nested semantics
• class Nested extends WLink

• Foreign key semantics
• class FK extends WLinkEnd
• reference sourceElement container source
