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 BASE_RESOURCE_COMMONS_R0.
• Look at 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 S2S_PERSIST_RESOURCES_R0, or together with it.
