Deliverable 1

Generalising the Traditional Wiki Systems to New Media Page Formats

Purpose:

To add a clever direct messaging system to web portal like Yioop. The motive behind this deliverable is to setup a pre-defined group that will enable direct messaging between users of Yioop.

Description:

Yioop follows the model-view-controller (MVC) software design pattern, so the models that create/edit users and groups in Yioop were used to add said pre-defined groups called "Chats" though the "accountaccescomponent" controller.

Code Snippet from controller when creating New Users:
