Hypertext
Publishing Progress
by Chris Peterson
Over twenty years after it was first envisioned, the goal of
hypertext publishing is finally near. As late as a year ago
interest in a system for publishing, not just swapping
stand-alone hypertexts, was still confined to a few scattered
proponents. As a last resort, FI was even considering trying to
fund development of a system ourselves, since the commercial
sector seemed so uninterested. But now this has changed.
Why has interest in the topic bloomed after so many years?
Ironically, much of it may be traceable to a misunderstanding.
When Apple Computer was ready to bring out a new software
construction kit named "Wildcard," they found the name
already taken, and the owner unwilling to sell it. (Files created
by the final program are still labeled internally as created by
"WILD.") Marketing settled on the substitute name
"HyperCard." Long-time hypertext proponents were
annoyed by the name and by advertising which touted the product
as hypertext, since HyperCard is not hypertext as the word had
been used. They correctly assumed that confusion would result.
But as Xanadu hypertext
pioneer Ted
Nelson has pointed out, the publicity has been good for
hypertext: people assumed that if Apple was interested in
hypertext, it must be good. Suddenly it was all the rage, and in
this avalanche of interest there were a few farsighted people who
focused on the original vision. And those people are making all
the difference.
John Walker of Autodesk,
who had been interested in hypertext long before HyperCard, is
said to have assumed that (surely!) some large company was
funding hypertext development. He was reportedly appalled to find
instead that the classical hypertext development group, Xanadu,
was scraping along on volunteer labor. Fortunately, as chairman
of Autodesk--a company best known for its highly-popular AutoCAD
computer aided design products--he was in a position to solve
this problem.
Arranging for Autodesk to acquire 80% of Xanadu Operating Company
was a challenge: in its many years of struggling corporate
existence Xanadu had accumulated many stakeholders and piles of
confusing legal paperwork. Closing the deal became a task for
Roger Gregory (longtime leader of the group) working with Phil
Salin of the aptly-named consulting team, Venture Acceleration.
The heartfelt thanks of all of us who've longed for real
hypertext go to these three people.
A side note: we were pleased to hear from John Walker that FI's
president Eric Drexler played a role in this as well: the vision
of hypertext publishing presented in his book, Engines of Creation,
helped convince Autodesk to proceed with the unorthodox deal.
Now Xanadu is rolling: the company has offices, equipment, and a
programming team at work turning out product. At this spring's
West Coast Computer Faire they announced plans to release their
first product within 18 months. This will be hypertext software
for individuals and small groups of under ten people, using
technology of the sort needed for a full public hypertext
publishing system, and providing a stepping stone toward the
larger system.
The Xanadu system is divided conceptually into two parts, the backend
and the frontend. The backend handles storage,
retrieval, versioning, linking, and editing of data with no
knowledge of the nature of the data being handled, and with no
direct contact with the user. Frontends are advanced application
packages that:
- interact with users,
- interface to input and output devices,
- interpret the stored data as text, graphics, or music,
- format data for display,
- incorporate numeric manipulations and other operations to
be carried out on data,
- are specialized to serve particular market needs,
- create, implement, and manage the metaphors for working
in hypertext and hypermedia environments.
Frontends for Xanadu will be primarily produced by third party
developers. Late this year, experimental versions of the backend
software will begin to be licensed to researchers and advanced
software developers interested in starting hands-on hypertext
experience and thinking about design issues for front-end
software. (The functionalities of the experimental version will
be carried forward in the software product, but the syntax is
expected to change.) Such developers should write for further
information: Xanadu Operating Company, 550 California Ave., Suite
101, Palo Alto, CA 94306, Attn: Gayle Pergamit.
See above
note.
Interest in hypertext publishing now extends beyond Xanadu. ON
Technology--run by Mitch Kapor, founder of Lotus Development--is
developing an object-oriented software platform which could be
extended to support hypertext publishing. ON is rumored to be
considering this possibility, which may be within reach now that
(according to MacWeek) they have obtained $3 million
in venture capital.
Apple has formed a working group on "collaborative
hypertext." Combine this with their existing efforts in
hypertext and it adds up to real interest; Apple will have a big
impact on this field if it chooses.
Keep an eye on Doug Engelbart & Co. too; as a hypertext
pioneer he is well-placed to stimulate the creation of a valuable
system. He and colleagues Howard Franklin and Christina Engelbart
have not yet announced their plans, but if Doug doesn't build a
new system himself, he will inspire further efforts by others.
In the nonprofit sphere, software developers are aiming to
incorporate hypertext publishing features into USENET, the giant
international computer network running on UNIX-based computers.
Several brainstorming meetings were held in the San Francisco
area in May, led by Eric Raymond (eric@snark.uucp or
uunet!snark!eric).
Meanwhile Kirk Kelley at Sun Microsystems is working to ensure
that the various hypertext systems will be able to exchange
information. This is a critical effort--having conflicting
standards in hypertext publishing would be like having
conflicting standards for phone lines or fax machines: isolated
systems would offer inferior service, hampering communication and
the growth of knowledge (but eventually linking up or
disappearing).
There is enough known activity that there are likely to be other
hypertext publishing efforts still under wraps. We'll try to keep
you up to date in these pages, since so many FI participants have
an intense interest in this field. Another publication to watch
is the new magazine HyperAge, six issues a year for
$20 in the US. To subscribe using a credit card, call

'Human
Frontiers' Advances
Although its technical scope has been refined and its budget
cut, Japan's proposed international Human Frontiers Science
Program is still relevant to development of both nanotechnology
and artificial intelligence. The Economist calls the
planned effort "the world's first truly international
government research program."
Originally budgeted at $6 billion to be spent over twenty years,
with Japan contributing about half of the funds, Frontiers'
initial goals were very broad and, some said, overambitious: from
neural-style computing to "the elucidation of biological
functions." Even Japan's former Prime Minister Yasuhiro
Nakasone, a strong promoter of the program, criticized its
vagueness. A one-year $1.4 million study to clarify these goals
was completed in spring 1988 and reviewed by scientists from the
Western summit nations and the European Community, who advocated
an immediate start on the program.
The new refined goals are (1) to study the higher-order functions
of the brain, especially its ways of visualizing objects and
understanding words, and (2) molecular recognition and response
functions. The new proposed budget is $60-100 million, to be
spent on 30-50 three-year research grants, 100-200 post-doc
fellowships, and 10-20 workshops.
Frontiers got a boost from the June 1988 economic summit of
Western nations, when it was endorsed in the final communiqué:
"We note the successful conclusion of the Japanese
feasibility study on the Human Frontiers Science Program and are
grateful for the opportunity our scientists were given to
contribute to the study. We look forward to the Japanese
government's proposals for implementation of the program in the
near future."
Japanese officials had originally hoped to get the other six
summit nations--Canada, Britain, France, Italy, West Germany, and
the U.S.--to commit funds to the project at the summit, but not
surprisingly these nations are waiting for Japan to make a
commitment first. The communiqué's statement of support will
strengthen the position of the program's advocates, the Science
and Technology Agency and the Ministry for International Trade
and Industry, when they approach the Ministry of Finance for
funds later in 1988.
In a move unprecedented in Japan, these agencies propose that the
program be run by an international foundation to be established
in Switzerland, and to be funded entirely by Japan in the initial
phase (at least $20 million in fiscal year 1989). The U.S.
National Science Foundation and the European Community will
provide experienced personnel for the administrative secretariat,
and scientists from all summit nations will participate in the
governing council and peer review committees.
Books
of Note
Books are listed in order of increasing specialization and
level of reading challenge. Your suggestions are welcome.--Editor
Prisons We Choose to Live Inside, by Doris
Lessing, Harper & Row, 1987, paper, $6.95. A small book with
high impact, as asserted on the cover. An eloquent plea for
integrating what little we know of the social sciences into
education, to help us primates stop repeating Milgram
experiment-type horrors.
Moving Mountains, by Henry M. Boettinger,
Collier Macmillan, 1975, paper, $5.95. A practical treatise on
convincing others to share your ideas. "The first truly
modern and truly searching essay on rhetoric--in the classical
meaning of the term--in the last three or four hundred
years."--Peter Drucker
The Social Brain, by Michael S. Gazzaniga,
Basic Books, 1987, paper, $8.95. A neuroscientist argues that the
brain is more a social entity, a vast confederacy of relatively
independent modules, each of which processes information and
activates its own thoughts and actions. This view has some
similarity to Minsky's Society of Mind theory. The writing is
anecdotal and enjoyable.
The Visual Display of Quantitative Information,
by Edward R. Tufte, Graphics Press, 1983, hardcover, $34. A
beautiful book explaining the right ways (and ridiculing the
wrong ways) to present numerical information. Amusing and
visually enjoyable, it inspires the reader to support Tufte's
high standards. Fun to browse; makes a great gift.
How Superstition Won and Science Lost, by
John C. Burnham, Rutgers, 1987, paper, $16. Tracks the decline in
the quality of science popularization by the media over the past
century and shows how this has undermined the impact of science
and strengthened the forces of irrationalism.
What Sort of People Should There Be?, by
Jonathan Glover, Pelican, 1984, paper, $5.95. An Oxford
philosopher looks at the emotional and ethical issues raised by
(hypothetical) advanced technologies able to alter the human
form, control the brain, and create artificial intelligences.
Covers such topics as possible abuse of the technologies, and
what people will do once there is no need to "work."
Neurophilosophy, by Patricia Smith
Churchland, MIT Press, 1986, hardcover, $29.95. Begins with the
neurosciences, then proceeds through AI, connectionist research,
and philosophy to give a picture of how the brain works.
Skillfully written and very readable.
Evolutionary Epistemology, Theory of Rationality, and
the Sociology of Knowledge, ed. by Gerard Radnitzky
and W.W. Bartley, III, Open Court, 1987, paper. A collection of
essays on a powerful theory of how knowledge grows: by evolution
through variation and selective retention. Treats knowledge as an
objective evolutionary product, and offers insights into
evolutionary processes in general. Authors include Sir Karl
Popper.
Neural Darwinism, by Gerald Edelman, Basic
Books, 1987, hardcover, $29.95. Having won a Nobel Prize for his
work in immunology, the author now examines how the brain works,
presenting his theory of neuronal group selection. A difficult
book with significant ideas.
