= Analysis =

== Overview ==
This task is the second task of the [wiki:GROUP_RESOURCE_MODEL_REDESIGN_R0]. Task`s goal is to present the file resource accesses and working logic for persistence. It`s also part of the refactoring of the model since all persisters should be refactored as well. 

== Task requirements ==
 * Complete and stable design of the mem and file accesses hierarchy.
 * Implementation of persistence keys and options.
 * Providing logic for serialization of changes and model. 
 * Refactoring of all current persisters and writing more for the new model objects like changes and immlist. 

== Task result ==
The result will be source code and documentation of aspects of the new designs that were too specific to be part of the major redesign documentation. 

== Implementation idea ==
 * Read the [wiki:GROUP_RESOURCE_MODEL_REDESIGN_R0] and [wiki:GROUP_MEM_RESOURCES_MODEL_R0]

== How to demo ==
Save and load a sophie 2 book one afterhow the new hierarchy and demonstrate that all of the tests work.
