     1.5 +\label{cha:opl}
     1.6 +
     1.7 +Version 1.0, 8 June 1999
     1.8 +
     1.9 +\section{Requirements on both unmodified and modified versions}
    1.10 +
    1.11 +The Open Publication works may be reproduced and distributed in whole
    1.12 +or in part, in any medium physical or electronic, provided that the
    1.13 +terms of this license are adhered to, and that this license or an
    1.14 +incorporation of it by reference (with any options elected by the
    1.15 +author(s) and/or publisher) is displayed in the reproduction.
    1.16 +
    1.17 +Proper form for an incorporation by reference is as follows:
    1.18 +
    1.19 +\begin{quote}
    1.20 +  Copyright (c) \emph{year} by \emph{author's name or designee}. This
    1.21 +  material may be distributed only subject to the terms and conditions
    1.22 +  set forth in the Open Publication License, v\emph{x.y} or later (the
    1.23 +  latest version is presently available at
    1.24 +  \url{http://www.opencontent.org/openpub/}).
    1.25 +\end{quote}
    1.26 +
    1.27 +The reference must be immediately followed with any options elected by
    1.28 +the author(s) and/or publisher of the document (see
    1.29 +section~\ref{sec:opl:options}).
    1.30 +
    1.31 +Commercial redistribution of Open Publication-licensed material is
    1.32 +permitted.
    1.33 +
    1.34 +Any publication in standard (paper) book form shall require the
    1.35 +citation of the original publisher and author. The publisher and
    1.36 +author's names shall appear on all outer surfaces of the book. On all
    1.37 +outer surfaces of the book the original publisher's name shall be as
    1.38 +large as the title of the work and cited as possessive with respect to
    1.39 +the title.
    1.40 +
    1.41 +\section{Copyright}
    1.42 +
    1.43 +The copyright to each Open Publication is owned by its author(s) or
    1.44 +designee.
    1.45 +
    1.46 +\section{Scope of license}
    1.47 +
    1.48 +The following license terms apply to all Open Publication works,
    1.49 +unless otherwise explicitly stated in the document.
    1.50 +
    1.51 +Mere aggregation of Open Publication works or a portion of an Open
    1.52 +Publication work with other works or programs on the same media shall
    1.53 +not cause this license to apply to those other works. The aggregate
    1.54 +work shall contain a notice specifying the inclusion of the Open
    1.55 +Publication material and appropriate copyright notice.
    1.56 +
    1.57 +\textbf{Severability}. If any part of this license is found to be
    1.58 +unenforceable in any jurisdiction, the remaining portions of the
    1.59 +license remain in force.
    1.60 +
    1.61 +\textbf{No warranty}. Open Publication works are licensed and provided
    1.62 +``as is'' without warranty of any kind, express or implied, including,
    1.63 +but not limited to, the implied warranties of merchantability and
    1.64 +fitness for a particular purpose or a warranty of non-infringement.
    1.65 +
    1.66 +\section{Requirements on modified works}
    1.67 +
    1.68 +All modified versions of documents covered by this license, including
    1.69 +translations, anthologies, compilations and partial documents, must
    1.70 +meet the following requirements:
    1.71 +
    1.72 +\begin{enumerate}
    1.73 +\item The modified version must be labeled as such.
    1.74 +\item The person making the modifications must be identified and the
    1.75 +  modifications dated.
    1.76 +\item Acknowledgement of the original author and publisher if
    1.77 +  applicable must be retained according to normal academic citation
    1.78 +  practices.
    1.79 +\item The location of the original unmodified document must be
    1.80 +  identified.
    1.81 +\item The original author's (or authors') name(s) may not be used to
    1.82 +  assert or imply endorsement of the resulting document without the
    1.83 +  original author's (or authors') permission.
    1.84 +\end{enumerate}
    1.85 +
    1.86 +\section{Good-practice recommendations}
    1.87 +
    1.88 +In addition to the requirements of this license, it is requested from
    1.89 +and strongly recommended of redistributors that:
    1.90 +
    1.91 +\begin{enumerate}
    1.92 +\item If you are distributing Open Publication works on hardcopy or
    1.93 +  CD-ROM, you provide email notification to the authors of your intent
    1.94 +  to redistribute at least thirty days before your manuscript or media
    1.95 +  freeze, to give the authors time to provide updated documents. This
    1.96 +  notification should describe modifications, if any, made to the
    1.97 +  document.
    1.98 +\item All substantive modifications (including deletions) be either
    1.99 +  clearly marked up in the document or else described in an attachment
   1.100 +  to the document.
   1.101 +\item Finally, while it is not mandatory under this license, it is
   1.102 +  considered good form to offer a free copy of any hardcopy and CD-ROM
   1.103 +  expression of an Open Publication-licensed work to its author(s).
   1.104 +\end{enumerate}
   1.105 +
   1.106 +\section{License options}
   1.107 +\label{sec:opl:options}
   1.108 +
   1.109 +The author(s) and/or publisher of an Open Publication-licensed
   1.110 +document may elect certain options by appending language to the
   1.111 +reference to or copy of the license. These options are considered part
   1.112 +of the license instance and must be included with the license (or its
   1.113 +incorporation by reference) in derived works.
   1.114 +
   1.115 +\begin{enumerate}[A]
   1.116 +\item To prohibit distribution of substantively modified versions
   1.117 +  without the explicit permission of the author(s). ``Substantive
   1.118 +  modification'' is defined as a change to the semantic content of the
   1.119 +  document, and excludes mere changes in format or typographical
   1.120 +  corrections.
   1.121 +
   1.122 +  To accomplish this, add the phrase ``Distribution of substantively
   1.123 +  modified versions of this document is prohibited without the
   1.124 +  explicit permission of the copyright holder.'' to the license
   1.125 +  reference or copy.
   1.126 +
   1.127 +\item To prohibit any publication of this work or derivative works in
   1.128 +  whole or in part in standard (paper) book form for commercial
   1.129 +  purposes is prohibited unless prior permission is obtained from the
   1.130 +  copyright holder.
   1.131 +
   1.132 +  To accomplish this, add the phrase ``Distribution of the work or
   1.133 +  derivative of the work in any standard (paper) book form is
   1.134 +  prohibited unless prior permission is obtained from the copyright
   1.135 +  holder.'' to the license reference or copy.
