= Analysis =


== Overview ==
Different kind of resources are going to be persisted on th Sophie2 server - users, books, etc. For now, resources are stored in a database. We should not allow this database to be bloated, so a way for cleaning it up must be defined.

== Task requirements ==
Design and implement a model for S2S database archiving. Think about the following aspects:
 * Archiving old resource changes.
 * Dealing with old comments.
 * Archiving unused accounts. [[BR]]
Make decisions on these and apply them to the org.sophie2.server.persistence layer.

== Task result ==
Source code - extra features in org.sophie2.server.persistence.

== Implementation idea ==
1st: Implement this task after (or together with) [wiki:S2S_PERSIST_CHANGES_R0]. The problem here is that this task is in the next revision. [[BR]]
2nd: Think out just the mechanism for archiving, apply it to the currently persisted objects. Changes' shrinking can be implemented with the next (main) revision.
