Open Source Licenses in Common Vision Blox

SQLite Copyright

SQLite is in the

Public Domain <http://en.wikipedia.org/wiki/Public_Domain>

All of the code and documentation in SQLite has been dedicated to the

public domain <http://en.wikipedia.org/wiki/Public_Domain> by the

authors. All code authors, and representatives of the companies they

work for, have signed affidavits dedicating their contributions to the

public domain and originals of those signed affidavits are stored in a

firesafe at the main offices of Hwaci <http://www.hwaci.com>. Anyone is

free to copy, modify, publish, use, compile, sell, or distribute the

original SQLite code, either in source code form or as a compiled

binary, for any purpose, commercial or non-commercial, and by any means.

The previous paragraph applies to the deliverable code and documentation

in SQLite - those parts of the SQLite library that you actually bundle

and ship with a larger application. Some scripts used as part of the

build process (for example the "configure" scripts generated by

autoconf) might fall under other open-source licenses. Nothing from

these build scripts ever reaches the final deliverable SQLite library,

however, and so the licenses associated with those scripts should not be

a factor in assessing your rights to copy and use the 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

<http://www.hwaci.com/>, 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 insufficient. You must also send by surface mail a
