= Analysis =

== Overview ==
The current model and resources design does not support the needed functionality for changes manipulation. This task's main goal is to present a complete redesign of the internal concepts for resources and sophie 2 model. This will result in a major refactoring of the base and main model modules.  

== Task requirements ==
 * Complete and stable design which supports all needed functionality.
 * Decomposing of this task to smaller weekly tasks.
 * Providing a schedule with deadlines for their completion. 
 * Provide the other developers with a prototype of the new model as soon as possible because they are blocked by this task.    

== Task result ==
The result will be prototype source code and detailed documentation of the new design. 

== Implementation idea ==
 * Use the design draft posted by milo in http://pastebin.asteasolutions.net/f444cc8f1.
 * Create a new module for the new resources that separates the new logic so that the old one is working until a full implementation.

== How to demo ==
This task is mainly redesign and its result is mainly documentation of the new design. 
There will be major quantity of tests provided.
