The current version of the WissKI software is based on the most up-to-date version of the content management system Drupal - Drupal 8 -. The functionality of Drupal can be extended and modified by third-party modules. The WissKI system is accordingly a set of subdivided into logical units modules, each bringing encapsulated functionality in the system. The modules rely on all core functionality of Drupal, so that all common features of Drupal such. maintain the user control with detailed rights management or the creation of web pages.
With Drupal 7 the contents of the content management system Drupal were abstracted. As a result, since then all content - regardless of whether it is web pages, comments, forums or user profiles - are uniformly manageable and customizable and manageable through the common system interfaces. The contents in Drupal are summarized in so-called "Entity Types", z. "Web pages" (Node), "User Profiles", "Comments". These can be further specialized through "bundles": "regular websites" (Page) or "short articles" (Article) are subcategories of Node. The data itself is instantiated in the form of so-called "entities" and stored. The "fields" of entities are defined per bundle and can then be filled entity-specifically. The storage of the entities and filled fields is done in Drupal regularly by the connected database system in the form of tables. The Entity Reference field, a specially implemented data field, allows Drupal to reference any bundle from a bundle, generating submasks of any complexity and depth.
