= Analysis =


== Overview ==
Every resource should have meta information, which consists of:
 * The author of the resource
 * The date the resource was created
 * Version of the resource
 * The date the resource was last modified
 * Who was the last that modified the resource
 * The dimensions of the image (if the target of the resource is an image)
 * etc.

== Task requirements ==
 * Get familiar with the resource concepts, described in [wiki:BASE_RESOURCE_COMMONS_R0].
 * Look at [wiki:S2S_PERSIST_RESOURCES_R0] to understand how the resources will be stored on the server.
 * Discuss and decide how to store the meta information for every resource (for example, if resources are persisted in a database, their corresponding meta could be stored in a separate table).
 * In the persistence layer of the server, add functionality for dealing with meta information.
 * Write appropriate unit tests.

== Task result ==
Source code (updated org.sophie2.server.persistence module with basic implementation of meta concepts), unit tests.

== Implementation idea ==
Implement this task after [wiki:S2S_PERSIST_RESOURCES_R0], or together with it. 

== Related ==

== How to demo ==
Show the persistence module with the new class(es), run the unit tests.
