Case Study - PHP Data Services To Extract Content from Drupal Database

In this case study " PHP Data Services Extract Content from Drupal Database", I intended to present how Data Service concepts can be applied to extract data with marketing value from a CMS database and publish it as web services. I used the drupal instance deployed at http://wso2.org as the CMS for the use case. And as the data service framework, I used WSF/PHP data services library, as it requires minimum changes to the existing infrastructure (the LAMP stack).
