File level metadata applies to all the code within the file and should be placed at the top of the file:
<?php
/**

* @copyright MIT
*/
If a class extends another class and would use the same metadata, providing it @inheritDoc is a simple way for use the same documentation. If multiple classes inherit from a base, only the base would need to be changed for the children to be affected.
abstract class FooBase
{
