Most folks who use DAML+OIL, soon to be WebOnt, to define
an ontology I th9ink feel they are done without any other material,
as the best practice is to put the descriptions into the ontology docuement
where they are explicitly associated with the properties being defined.
http://www.daml.org/ontologies/uri.html  lists a whole bunch of ontologies
defined in DAML.

Hang on - SVG is human-readable, as is MathML and X3D -- all are langauges
for material to be presentedto a human.  We are not talking about making the
source human-readble I hope.

RDF is an interesting case but making it human-readable is doable in orll
sorts of ways.  You can use a style sheet (@@ example on line?) and you can
use RDF schema information to give you ways of represnting properties and
classes, and you can use knowledge of things like titles to represent other
things, so in many cases making an RDF file human readable is a
straightforward excercise. Eric Miller has an RDF schema viewer somewhere
