Appendix E Open Source Licences
might fall under other licenses. The details here are unclear. We do not worry
about the licensing of the documentation and build code so much because none of
these things are part of the core deliverable SQLite library.
All of the deliverable code in SQLite has been written from scratch. No code has
been taken from other projects or from the open internet. Every line of code can
be traced back to its original author, and all of those authors have public domain
dedications on file. So the SQLite code base is clean and is uncontaminated with
licensed code from other projects.
Obtaining An Explicit License To Use SQLite
Even though SQLite is in the public domain and does not require a license, some
users want to obtain a license anyway. Some reasons for obtaining a license
include:
•You are using SQLite in a jurisdiction that does not recognize the public domain.
•You are using SQLite in a jurisdiction that does not recognize the right of an
author to dedicate their work to the public domain.
•You want to hold a tangible legal document as evidence that you have the legal
right to use and distribute SQLite.
•Your legal department tells you that you have to purchase a license.
If you feel like you really have to purchase a license for SQLite, Hwaci, the
company that employs the architect and principal developers of SQLite, will sell
you one.
Contributed Code
In order to keep SQLite completely free and unencumbered by copyright, all new
contributors to the SQLite code base are asked to dedicate their contributions to
the public domain. If you want to send a patch or enhancement for possible
inclusion in the SQLite source tree, please accompany the patch with the following
statement:
The author or authors of this code dedicate any and all copyright interest in this
code to the public domain. We make this dedication for the benefit of the public at
large and to the detriment of our heirs and successors. We intend this dedication
to be an overt act of relinquishment in perpetuity of all present and future rights
to this code under copyright law.
We are not able to accept patches or changes to SQLite that are not accompanied
by a statement such as the above. In addition, if you make changes or
enhancements as an employee, then a simple statement such as the above is
