  • Node.hasParentNode
  • Node.{ordered list of subordinates} - via rdf:Seq subordinate of the rss:items
  • Node.{weight of subordinates}
  • Node.hasCreator - dc:creator
  • Node.creationDate - dc:created
  • Node.modificationDate - dc:modified
  • Node.nodeTitle - rss:item.title
  • Node.nodeDescription - rss:item.description
  • Node.hasNodeType - refine dcmitypes?
  • Node.hasURL - rss:item.link
  • Node.hasURI - implicitly via rdf:about→rss:item
  • Node.hasIcon

• Right
  • hasTargetAgent
  • hasRightType
  • hasParentNodeType
