The author(s) and/or publisher of an Open Publication-licensed document
may elect certain options by appending language to the reference to or
copy of the license. These options are considered part of the license
instance and must be included with the license (or its incorporation by
reference) in derived works.
A. To prohibit distribution of substantively modified versions without the
explicit permission of the author(s). "Substantive modification" is
defined as a change to the semantic content of the document, and excludes
mere changes in format or typographical corrections.
To accomplish this, add the phrase `Distribution of substantively modified
versions of this document is prohibited without the explicit permission of
the copyright holder.' to the license reference or copy.
B. To prohibit any publication of this work or derivative works in whole
or in part in standard (paper) book form for commercial purposes is
prohibited unless prior permission is obtained from the copyright holder.
To accomplish this, add the phrase 'Distribution of the work or derivative
of the work in any standard (paper) book form is prohibited unless prior
permission is obtained from the copyright holder.' to the license
reference or copy.
