Zettelkasten

hierarchical documentation & reference trees

originally done with filing cards

(because that was all there was)

computers can do the same, now

my suggestion:

flat factbase of notes

tags

queries on tags, backtracking (e.g. PROLOG)

there are many ways to traverse a knowledge base

one query for each traversal

author supplies “starting” queries

users create “extra” queries

extra queries can be contributed to the community

new tags created by queries

tags are just an “optimization” for often used queries (PROLOG rules can build up new tags, then query them, at the expense of compute time)

Arrowgrams + backtracking matcher

one Component for each query
