#AHypothesis of #pkmDesign - the power of modern PKMs is captured the most in three basic file formats:

- free-form flowing text, usable for outlining with bullets and long-form writing. Ideally it supports increased degrees of advanced formating. Individual segments can be elevated into structured data.

- OPML-like structure-first systems for personal databases. Stores things with high native categorization.

- Free-form Canvas tool for connecting other two file types and free drawings.
