- Node - rss:channel or rss:item depending on context, alternatively dcmitypes:Collection when a folder
- Node.hasChildNode - rss:items
- 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
- Node.isFolder - rss:channel and/or dcmitypes:Collection
- User - foaf:Person
- Group - group is a special kind of User entity - foaf:Group
- User.hasMember - applicable to Group only - foaf:hasMember
- User.isMemberOf - applicable to User only - as inverse of foaf:hasMember
- User.hasURI - rdf:about
- User.hasLogin - foaf:holdsAccount→foaf:OnlineAccount→foaf:accountName
- User.hasName - foaf:name
- User.hasPass - unavailable via RDF serialization
- User.isGroup - via foaf:Group
- User.hasEmail - SHA1-encoded - foaf:mbox_sha1sum

- User.hasCountry
- User.hasNote
