One of the core tasks of Liip was the development of the content management system and a document management system, that allowed the extensive use of metadata (e.g. product line information). As a result, every Migros branch can for example show documents and messages related to their product line. Different permission levels can be individually assigned to take into account a wide range of organisational units, each with different staff levels.
Liip opted for the open-source content management system Drupal because of its effective standard functionality. This CMS satisfied most of the programming requirements. Symfony 2 was also used to integrate interfaces and other middleware. This open-source architecture offers greater vendor independence compared to the previous proprietary product.
