= Analysis =

== Overview ==
 This that is about the extensibility of the persistence format of Sophie 2.0. The persistence format should provide an extension point for new things to be persisted.
== Task requirements ==
 * Design a way to persist new things.
  * If the client implements a new plug-in that uses something which may be persisted, the format should provide him the ability to do so.
  * Persisting new should should be independent regarding the original Sophie 2.0 format.
 * Sophie 2.0 persisting format should provide extension point for persisting.
  * Everything that is to be persisted from a certain point on, should  be declared as an extension to the persisting format of Sophie 2.0
 * Provide a wiki page that fully describes the way the client should implement new extensions for the persistence format.
 * Write unit test with a mock extension of the format that tests its extensibility capabilities.
 * All important wiki content should be put in the corresponding section of a wiki page => [wiki:BASE_PERSISTENCE]

== Task result ==
 * Source code.
 * Wiki page.
 * Unit Tests.


== Implementation idea ==
 * view code:
  * => [source:trunk/sophie2-platform/modules/org.sophie2.base.persistence]
  * => [source:trunk/sophie2-platform/modules/org.sophie2.main.model.book.format.r1/src/main/java/org/sophie2/main/model/book/format/r1]
  * => [source:trunk/sophie2-platform/modules/org.sophie2.main.model.book.format.r2/src/main/java/org/sophie2/main/model/book/format/r2]
 * create the extension point of the format after a thorough design.
 * create a wiki page named "BASE_PERSISTENCE_FORMAT_POINT" and provide explanation of how to create an extension to the format.
 * write unit test with mock extension.

 * Show the wiki page that describes the extensibility.
 * Run unit tests.
