Hypertext is frequently organized as a hierarchy. A tree structure helps organize information. The path from root to node is easily displayed, providing context to the current page. The top-levels of the hierarchy may provide an index into the lower levels. (cbb 4/07)

Quote: Hypertext should have a strong preference for tree structures [»mccrDL10_1984]
Quote: a node of a Hypertext hierarchy can be a frame or another Hypertext [»stotPD12_1988]
Quote: all Hypertext systems should support hierarchies of inclusion relations; these should be distinct from reference links [»halaFG7_1988]

Subtopic: hierarchy in KMS up

Quote: most KMS databases are strongly hierarchical [»akscRM7_1988a]
Quote: top levels of the KMS hierarchy is an index; lower levels represent documents and task-related groups of information [»akscRM7_1988a]
Quote: the 'skeleton' for a KMS database is a multi-level hierarchy [»akscRM7_1988a]

Subtopic: process a hierarchy of frames up

Quote: with hierarchical organization; users want to operate on subtrees [»akscRM5_1984]
Quote: KMS programs often process a hierarchy of frames; e.g., a document is generated from a hierarchy [»akscRM7_1988a]

Subtopic: hierarchy in NoteCards up

Quote: a NoteCards filebox provides hierarchical categorization for storing and retrieving notecards [»halaFG7_1988]
Quote: some writers have abandoned NoteCards in favor of outline processors since fileboxes can not be expanded or collapsed [»halaFG7_1988]
Quote: experienced NoteCards users put all notes in one filebox and use a sketch card to form related piles; when stable, turned into fileboxes [»halaFG7_1988]
