_1 What is Xanadu?
------------------

_1a
  Xanadu is a trade and service mark of Project Xanadu for computer
  software and services for electronic publishing and media
  manipulation.  See question 3_ below for Project Xanadu contact
  details.

_1b
  Xanadu is the original hypertext and interactive multimedia
  system, under continuous development since 1960.  See question 4_
  below for the history of the Xanadu system.

_1c
  Xanadu is an overall paradigm - an ideal and general model for all
  computer use, based on sideways connections among documents and
  files.  This paradigm is especially concerned with electronic
  publishing, but also extends to all forms of storing, presenting
  and working with information.  It is a unifying system of order
  for all information, non-hierarchical and side-linking, including
  electronic publishing, personal work, organisation of files,
  corporate work and groupware.

  All data (for instance, paragraphs of a text document) may be
  connected sideways and out of sequence to other data (for
  instance, paragraphs of another text document).  This requires new
  forms of storage, and invites new forms of presentation to show
  these connections.

  On a small scale, the paradigm means a model of word processing
  where comments, outlines and other notes may be stored
  conceptually adjacent to a document, linked to it sideways.  On a
  large scale, the paradigm means a model of publishing where anyone
  may quote from and publish links to any already-published
  document, and any reader may follow these links to and from the
  document.

_1d
  Xanadu is an ideal of open electronic publishing based on the
  paradigm mentioned in answer 1c_ above.  It is intended to be
  especially free and fair, where all authors and readers are
  considered equal.  It is a complete business system for electronic
  publishing based on this ideal with a win-win set of arrangements,
  contracts and software for the sale of copyrighted material in
  large and small amounts.  It is a planned world-wide publishing
  network based on this business system.  It is optimised for a
  point-and-click universe, where users jump from document to
  document, following links and buying small pieces as they go.

_1e
  The Project Xanadu (Australia) formal problem definition is:

  We need a way for people to store information not as individual
  "files" but as a connected literature.  It must be possible to
  create, access and manipulate this literature of richly formatted
  and connected information cheaply, reliably and securely from
  anywhere in the world.  Documents must remain accessible
  indefinitely, safe from any kind of loss, damage, modification,
  censorship or removal except by the owner.  It must be impossible
  to falsify ownership or track individual readers of any document.

  This system of literature (the "Xanadu Docuverse") must allow
  people to create virtual copies ("transclusions") of any existing
  collection of information in the system **regardless of ownership**.
  In order to make this possible, the system must guarantee that the
  owner of any information will be paid their chosen royalties on any
  portions of their documents, no matter how small, whenever and
  wherever they are used.


_2 What are the features of a Xanadu system?
--------------------------------------------
* Note: Some releases may not implement all of these features.

_2a
  Every Xanadu server is uniquely and securely identified.

_2b
  Every Xanadu server can be operated independently or in a network.

_2c
  Every user is uniquely and securely identified.

_2d
  Every user can search, retrieve, create and store documents.

_2e
  Every document can consist of any number of parts each of which
  may be of any data type.

_2f
  Every document can contain links of any type including virtual
  copies ("transclusions") to any other document in the system
  accessible to its owner.  Permission to link to a document is
  explicitly granted by the act of publication.

_2g
  Every document can contain a royalty mechanism at any desired
  degree of granularity to ensure payment on any portion accessed,
  including virtual copies ("transclusions") of all or part of the
  document.

_2h
  Every document is uniquely and securely identified.

_2i
  Every document can have secure access controls.

_2j
  Every document can be rapidly searched, stored and retrieved
  without user knowledge of where it is physically stored.

_2k
  Every document is automatically moved to physical storage
  appropriate to its frequency of access from any given location.

_2l
  Every document is automatically stored redundantly to maintain
  availability even in case of a disaster.

_2m
  Every Xanadu service provider can charge their users at any rate
  they choose for the storage, retrieval and publishing of
  documents.

_2n
  Every transaction is secure and auditable only by the parties to
  that transaction.

_2o
  The Xanadu client-server communication protocol is an openly
  published standard.  Third-party software development and
  integration is encouraged.

_4 What is the history of the Xanadu system?
--------------------------------------------

  Ted Nelson thought up the whole thing in 1960, and has been
  speaking and publishing about the idea since 1965.  In that year
  he also coined the terms "hypertext" and "hypermedia" for
  non-sequential writings and branching presentations of all types.
  (The term "interactive multimedia" seems to have become popular
  recently.)

  Since that time there have been a long series of changing designs
  embodying these ideas:

1960:
  Nelson's designs showed two screen windows connected by visible
  lines, pointing from parts of an object in one window to
  corresponding parts of an object in another window.  No existing
  windowing software provides this facility even today.

1965:
  Nelson's design concentrated on the single-user system and was
  based on "zipper lists", sequential lists of elements which could
  be linked sideways to other zipper lists for large non-sequential
  text structures.

1970:
  Nelson invented certain data structures and algorithms called the
  "enfilade" which became the basis for much later work (still
  proprietary to Xanadu Operating Company, Inc.)

1972:
  Implementations ran in both Algol and Fortran.

1974:
  William Barus extended the enfilade concept to handle
  interconnection.

1979:
  Nelson assembled a new team (Roger Gregory, Mark Miller, Stuart
  Greene, Roland King and Eric Hill) to redesign the system.

1981:
  K. Eric Drexler created a new data structure and algorithms for
  complex versioning and connection management.

  The Project Xanadu team completed the design of a universal
  networking server for Xanadu, described in various editions of Ted
  Nelson's book "Literary Machines" (see answer 6b_ below).

1983:
  Xanadu Operating Company, Inc. (XOC, Inc.) was formed to complete
  development of the 1981 design.

1988:
  XOC, Inc. was acquired by Autodesk, Inc. and amply funded, with
  offices in Palo Alto and later Mountainview California. Work
  continued with Mark Miller as chief designer.

  The 1981 design (now called Xanadu 88.1) was topped off but Miller
  began a redesign.  Xanadu 88.1 was not subjected to quality
  control or released as a product.

  Dean Tribble and Ravi Pandya became co-designers and work on the
  redesign continued.

1992:
  Autodesk entered into the throes of an organisational shakeup and
  dropped the project, after expenditures on the order of five
  million US dollars.  Rights to continued development of the XOC
  server were licensed to Memex, Inc. of Palo Alto, California and
  the trademark "Xanadu" was re-assigned to Nelson.

1993:
  Nelson re-thought the whole thing and respecified Xanadu
  publishing as a system of business arrangements.  Minimal
  specifications for a publishing system were created under the name
  "Xanadu Light", and Andrew Pam of Serious Cybernetics in
  Melbourne, Australia was licensed to continue development.

_7 What is the history of the name "Xanadu"?
--------------------------------------------

_7a
  Marco Polo mentioned the original palace "Shan-Du", somewhere
  near Beijing, in his autobiography.

_7b
  Samuel Taylor Coleridge published the poem "Kubla_Khan_",
  considered the sexiest in the English language, in the early 19th
  century. Supposedly Coleridge wrote a thousand lines in his mind
  while in an opiate trance, but was interrupted while trying to
  write it down by the infamous "person from Porlock" who bothered
  him on trivial business and made him forget the rest of the poem.
  This has been disputed by scholars who didn't believe there
  actually could have been any more to the poem.  Coleridge was
  inspired by the autobiography of Marco Polo mentioned in answer 7a_
  above, which he was reading.  See question 8_ below.

_7c
  Orson Welles, in his famous film "Citizen Kane", named the palace
  of Charles Foster Kane "Xanadu" after the Coleridge poem_.  It was
  based on the real life palace of San Simeon owned by William
  Randolph Hearst.

_7d
  Ted Nelson named his World Publishing Repository (trademark of
  Project Xanadu) project after the Coleridge poem_, to suggest "the
  magic place of literary memory where nothing is forgotten".

_7e
  The secret hideout of Mandrake the Magician in the comic strip of
  the same name was called "Xanadu" (presumably after the Coleridge
  poem_).

_7f
  The rock group Rush released a song called Xanadu, obviously
  inspired by "Kubla_Khan_", on their 1970s album "Farewell to
  Kings".

_7g
  The 1980 movie "Xanadu" starring Olivia Newton-John as a muse was
  also named after the Coleridge poem_, as an allusion to literary
  inspiration.  She also sang the title song.

_7h
  The pop group "Frankie Goes To Hollywood" released a 1984 album
  named "Welcome To The Pleasure Dome", on which the title song
  contains the line "In Xanadu did Kubla_Khan_ a pleasure dome
  erect".

_7i
  David Butler based the plot of his 1986 science-fiction novel
  "The Men Who Mastered Time" around the story of "Kubla_Khan_".

_7j
  Douglas Adams used the story of the creation of the Coleridge
  poem_ mentioned in answer 7b_ above as a central part of the plot of
  his science-fiction novel "Dirk Gently's Wholistic Detective
  Agency".

_7k
  Douglas Adams wrote a 1990 BBC Television documentary called
  "Hyperland" starring himself, former "Doctor Who" Tom Baker, Ted
  Nelson and many computer industry luminaries.  The documentary
  discussed the Xanadu system and quoted "Kubla_Khan_".


_8 What are the words to the Coleridge _poem "_Kubla_Khan"?
-----------------------------------------------------------

      In Xanadu did Kubla Khan
      A stately pleasure-dome decree:
      Where Alph, the sacred river, ran,
      Through caverns measureless to man,
    Down to a sunless sea.
    So twice five miles of fertile ground
    With walls and towers were girdled round:
    And here were gardens bright with sinuous rills,
    Where blossomed many an incense-bearing tree;
    And here were forests ancient as the hills,
    Infolding sunny spots of greenery.

    But oh! that deep chasm which slanted
    Down the green hill athwart a cedarn cover!
    A savage place! as holy and enchanted
    As e'er beneath a waning moon was haunted
    By a woman wailing for her demon-lover!
    And from this chasm, with ceaseless turmoil seething,
    As if this earth in fast thick pants were breathing,
    A mighty fountain momently was forced:
    Amid whose swift half-intermitted burst
    Huge fragments vaulted like rebounding hail,
    Or chaffy grain beneath the thresher's flail:

    And 'mid these dancing rocks at once and ever
    It flung up momently the sacred river.
    Five miles meandering with a mazy motion
    Through wood and dale the sacred river ran,
    Then reached the caverns measureless to man,
    And sank in tumult to a lifeless ocean:
    And 'mid this tumult Kubla heard from far
    Ancestral voices prophesying war!

      The shadow of the dome of pleasure
      Floated midway on the waves;
      Where was heard the mingled measure
      From the fountain and the caves.
    It was a miracle of rare device,
    A sunny pleasure-dome with caves of ice!

      A damsel with a dulcimer
      In a vision once I saw:
      It was an Abyssinian maid,
      And on her dulcimer she played,
      Singing of Mount Abora.
      Could I revive within me
      Her symphony and song,
      To such a deep delight 't would win me,
    That with music loud and long,
    I would build that dome in air,
    That sunny dome! those caves of ice!
    And all who heard should see them there,
    And all should cry, Beware! Beware!
    His flashing eyes, his floating hair.
    Weave a circle round him thrice,
    And close your eyes with holy dread,
    For he on honeydew hath fed,
    And drunk the milk of Paradise.

- Samuel Taylor Coleridge [1772-1834]
