Drupal is a content management system (CMS) and also a content management framework (CMF). Hence it’s both an application that enables non-programmers to build complex websites, and a framework that developers can use to quickly create custom functionality. There is a large and rapidly growing community that has developed around Drupal, which is passionate about improving the software and supporting its usage.
More than two years in the making, and containing 6,600 community-contributed commits, the release of Drupal 7 is imminent. Major changes have been made which impact end users, site builders and developers. This article explores the most notable new features, but first some Drupal basics for the uninitiated…
There are five layers in Drupal:
1. Data – These are ‘nodes’ (articles, comments, users).
2. Modules – Functional plug-ins to expand your site’s functionality.
3. Blocks & Menus – Provide output for sections of a page, which can include navigation.
4. User Permissions – Role-based, control what users can see and do.
5. Themes – Templates rendering the site in XHTML and CSS from the underlying data.
