Koutliner History
Much of the Hyperbole outliner design is based upon concepts pioneered in the Augment/NLS system, [Eng84a]. Augment treated documents as a hierarchical set of nodes, called statements, rather than cells. Every Augment document utilized this intrinsic structure.
The system could rapidly change the view of a document by collapsing, expanding, generating, clipping, filtering, including or reordering these nodes. It could also map individual views to multiple workstation displays across a network to aid in distributed, collaborative work.
These facilities aided greatly in idea structuring, cross-referencing, and knowledge transfer. The Koutliner is a start at bringing these capabilities back into the mainstream of modern computing culture.
