Drupal is an open source Content Management System (CMS) with elegant architecture and rich CMS functionality, that can be extended with pluggable modules. The modular nature of Drupal along with the availabillity of a wealth of existing modules makes it a powerful platform for implementing a variety of CMS use cases. Some of the core Drupal features that we like include: support for custom content types, taxonomies and RDFa. Drupal also provides hooks for customizing look and feel (theme) for any content. We like to use Drupal whereever the customer's use-cases match with the Drupal's CMS paradigm.
