HyperLinked Text (Hylt) is both a file format and a viewer for that
format. It uses (almost) flat text files to generate a Wiki-style
database of hyperlinked pages, without either the complex markup of
HTML or the esoteric database formats in which most Wikis store data.
It is geared towards users who desire a minimal interface between
them and their data or like to store their data in formats which can
be meaningfully stored in version control systems. It was developed
originally to match both of those goals, specifically for individuals
writing fiction and wishing to track inter-character and inter-location
relationships.
