h1: The ewok inheritance model (site administrators, content owners) Part of ewok's power lies in its inheritance model. At any level of your site, you can define file- or directory-level metadata or standard components (such as headers and footers) for pages, and have that information inherited by all directories and pages in the tree below. But since local objects override more global objects, you have flexibility to create objects that provide exactly the functionality you need and no more, having them inherit other functionality from objects higher up in the inheritance tree. This model gives you both easy maintenance of site-wide data, and the ability to customize specific pages, directories or sub-trees -- for example, at the root level of your site, you can create a global header, but override this with local versions in site subsections as required.
