[RDDL] new specification 20010305

[Jonathan Borden <jborden@mediaone.net>]

I've place an updated RDDL spec at:
http://www.rddl.org/ and a new version specific URL
http://www.rddl.org/20010305 .

This version contains only relatively minor edits and clarifies the URL
persistence policy. The URLs for the well known natures and purposes were a
mix of http://www.rddl.org/natures and http://www.rddl.org/natures.html. Now
only http://www.rddl.org/natures and http://www.rddl.org/purposes are
specified and should be used as these will be subdivided in subdirectories
in the future.

As promised some weeks ago, I've created a 'home' directory for RDDL
documents on the web at: http://www.rddl.org/home -- each document is of
course referenced as a rddl:resource, and this document is referenced as a
resource in the spec using a nature="http://www.rddl.org/" and
purpose="http://www.rddl.org/purposes#directory".

Enjoy.
