\chapter{Conditions of Distribution of the
World Wide Web Software}\lbrack THIS IS AN UNRATIFIED DRAFT PRELIMINARY
VERSION ONLY! This document is available
online as hypertext and in paper
form in postscript and plain text
versions.To date, the basic spirit
is correct, but some of the finer
details may change.  The public domain
bit HAS been ratified,see an official
document in PostScript
 or GIF (page
1 and page 2) \rbrack \par 
This is version 1.3 of these conditions,
dated 3 May 1993.
\section{Introduction}The World Wide Web, hereafter called
W3, is a global, computer networked
information system.\par 
The actual workings of the World
Wide Web software, its use and importance
are explained elsewhere. This document
deals only with the conditions of
distribution of CERN W3 software.\par 
The Conditions of Distribution respect
the general guidelines set forth
in a memorandum from the CERN management.\par 
A glossary aids understanding of
jargon terms. \par 
Thanks go to H. White ( SLAC ) for
some of the fundamental rules and
for comments and guidance.

\section{Goals of W3}The W3 project's goal is to provide
the High Energy Physics (HEP) community
with a collaboartive information
system independent of hardware and
software platform, and physcial location.
 The project spans technical design
notes, documentation, news, discussion,
educational material, personal notes,
publicity, bulletin boards, live
status information and physics data
as a uniform continuum, seamlessly
intergated with similar information
in other disciplines.\par 
The information is presented to the
user as a web of interlinked documents
.\par 
	Acces to information through W3 is:
\begin{itemize}
\item via a hypertext model;
\item network based, world wide;
\item information format independent;
\item highly  platform/operating system
independent;
\item scalable from local notes to distributed
data bases.
\end{itemize}Webs can be independent, subsets
or supersets of each other. They
can be local, regional or worldwide.
The documents available on a web
may reside on any computer supported
by that web.





\section{Anticipated audience}The public information provided today
on the Internet * is free. It is
aimed at academic and educational
use, but there are many governmental
and commercial bodies using the Internet.
W3 addresses primarily the academic
and educational world, but companies
can benefit from its use in-house
to maintain, read, write and publish
documents. Any public or private
body whose members are dispersed
over a wide area  and have network
access has a use for W3.\par 
The interested parties are either
developers or users. Users acquire
the software under conditions given
below, developers can either acquire
rights as set forth below, or join
in a more tight collaboration with
CERN, through the W3 Consortium.





\section{CERN W3 Software Products}W3 software comprises several distinct
types of software product:
\begin{itemize}
\item A Library of code common to the other
modules.
\item Browsers, (clients) which present
the information on a specific workstation.
\item Servers, which extract information
from existing file bases or from
data bases.
\item Gateways, which interface W3 to other
information systems.
\end{itemize}Some browsers, servers and gateways
have been written outside CERN, they
are based on the library of common
code, they are not subject to the
present conditions.\par 
In the development of the CERN software,
commercial tools have been used,
but the resulting code does not incorporate
software other than such as has been
expressly authorised for distribution.
\subsection{Library of Common Code}This has been constructed by CERN.
It is the basis of many of the other
products.
\subsection{Browsers}Three browsers have been constructed
by CERN:
\begin{itemize}
\item the Line-Mode browser, also "dumb-terminal"
browser, the lowest level interface
to W3.
\item the hypertext editor - browser for
NeXT workstations.
\item the browser for Apple Macintosh computers.
\end{itemize}These programs are subject to the
conditions.
\subsection{Servers}A generic server for use in a Unix
environment has been constructed
by CERN. It is the basis of all other
servers, and the prime example on
which to model other servers.\par 
Other specific servers have been
constructed at CERN. Their number
is variable: they are not listed
here. They are subject to the conditions.
\subsection{Gateways}These gateways among others have
been constructed by CERN:
\begin{itemize}
\item W.A.I.S. (Wide Area Information Services).
\item VMS Help (to DEC VAX/VMS help system).
\end{itemize}Note: access to the Gopher system
is incorporated into the library
of common code.





\chapter{General Condition applicable to all
uses}CERN is governed by the CERN Council,
which reserves the right in specific
cases to veto collaborations.\par 
CERN welcomes comments, but undertakes
no obligation for the maintenance
of the software, nor responsibility
for its correctness, and accepts
no liability whatsoever resulting
from the use of its software.





\chapter{Special Condition}This does not apply to software placed
in the public domain.\par 
CERN developed software is free to
the High Energy Physics community
throughout the world and to academic
institutes of the CERN member states
.\par 
Programs and documentation are provided
solely for the use of the organization
to which they are distributed, and
may not be redistributed or reproduced
in large numbers without the express
agreement of CERN. Note that such
agreement may have to be established
somewhere else in addition to or
instead of CERN in the case of programs
originating from sources outside
CERN. The material cannot be sold.
CERN should be given credit in all
references, library documentation,
and publications based on the programs.\par 
If the programs are modified beyond
what is necessary to adapt them to
the local machine/system environment,
it should be made clear in local
documentation that they are locally
modified versions of the CERN originals.
CERN should be informed of such modifications,
and given the possibility of introducing
the same modifications in the original
version. If local modifications are
so important as to change significantly
the behaviour of the program, its
name should also be changed in order
to avoid confusion with the original.





\chapter{Compensated Usage}This section does not apply to software
placed in the public domain.\par 
We distinguish several categories
of users. If a user is in more than
one category, then the most stringent
conditions of those categories applies.Military
users are specifically excluded from
all categories.
\section{Passive users}They use the W3 to access information
but do not themselves provide any
W3 support nor do they make data
available to themselves or to the
W3 user community.\par 
Rule: these users pay a nominal fee
per installed copy of browser modules.
See price list in appendix A (page
6).
\section{Information providers}They use W3 and make available data.
There are two categories:
\section{Providers of free information:}Rule: If the information is freely
available on the public Internet,
then there is no fee for use of the
software as long as the information
is maintained. If maintenace is stopped,
for whatever reason, CERN reserves
the right to reclassify the user
as a passive user. The rights include
all modules available from CERN.
\section{Users in closed systems:}Rule: If W3 is used within a closed
company or organisation, providing
no service to the outside, then that
organisation should pay a reasonable
commercial fee.\par 
Condition: any set consisting of
one browser type, one server type
and one gateway: single license 500
ECU, site license up to 500 users:
25 kECU, higher to be negotiated.
\section{Development Consortium members}These are companies or organizations
who wish to incorporate part or all
of the W3 software and/or ideas into
their own products, which they then
use and/or resell. \par 
Rule: Compensation should always
be made. A license will always be
non-exclusive.\par 
Condition: one of three standard
options can be negotiated for compensation
\begin{itemize}
\item in payment, at 20\% of CERN development
cost, currently 100 kECU,
\item in kind, as a sharing of source code
for a W3 related product with  other
consortium members, if this is of
interest to CERN;
\item in kind, by manpower contribution
to the software effort, consisting
in at least six months qualified
programmer effort on the CERN site.
\end{itemize}Successful applicants will be known
as members of the "World-Wide Web
consortium".
\section{Academic and Educational Government
Bodies of non-member states}These are large bodies who can benefit
from W3 in the running of their internal
information systems, but have no
commercial goals.\par 
Rule: These bodies should be treated
as developers. However, they will
usually be able and willing to contribute
to the W3 consortium by providing
manpower or computing resources to
strengthen the W3 project.Conditions:
as for developers.





\section{Price list}Software is available through network
access, there is no other distribution
method.\par 
Prices are in ECU or kECU (=1000
ECU).
