RSF: Themes and Variations
(2001)Abstract
?rsf? stands for Rigi Standard Form. Rigi is an information visualization
tool developed by Professor Hausi M¨uller at the University of
Victoria. Despite having the word ?standard? in the name, there
are two historically prevalent varieties of rsf, which have in the
past been called unstructured and structured. Usually when people
say rsf they mean the ?unstructured? variety. I think the structured/unstructured
distinction is a bit of a misnomer, so I?m going to refer to the
?unstructured? variety as three-tuple rsf. I?ll still refer to the
?structured? variety by its historically accepted name. I have recently
put together a new file format, which I?ve decided to call key-value
rsf. Since there were already two completely distinct file formats
parading around under the same name, it didn?t seem like such a
bad thing to add a third. And it saves me the trouble of having
to think up a new name. This document describes all three varieties
of rsf. The section on three-tuple rsf is an excerpt from the Rigi
manual. There is no other documentation for the keyvalue rsf. To
the best of my knowledge, there is also no other documentation for
the ?structured? rsf format.
