1.4.2 Simple as possible
Another design goal for the framework is the mantra ???Don??™t change PHP???. The PHP way is simple, pragmatic
solutions and so the Zend Framework is intended to reflect that simplicity in order to provide a simple solution
for mainstream developers. It is also powerful enough to allow for specialized usage via extension. The core
developers have done a great job in covering the common scenarios and providing ???flex-points??? to allow for
easy changing of the default behavior by those who want something more powerful or specialized.
1.4.3 Clean IP
All contributors to the Zend Framework have signed a Contributor License Agreement. This is an agreement
with Zend which defines intellectual property status of the contribution. That is, the contributor warrants that
(to the best of her knowledge), she is entitled to make the contribution and that no one else??™s intellectual
property rights are being infringed. This is intended to help protect all users of the framework from potential
legal issues related to IP and copyright. The risk is minimal, but with relatively recent actions by SCO against
AutoZone shows that a litigator going after the user of the allegedly copyright infringing code is a possibility.
As with everything, it is better to be prepared.
