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.
