public class SimpleRepo
extends java.lang.Object
implements org.ow2.weblab.core.services.ResourceContainer

This is a simple implementation of a ResourceContainer. It enable to save resource on a file system and get them after. It is a simpler version that the filerepository one. Main differences are:

• This version does not allocate uris; it means that incoming URIs has to be unique otherwise their will be some replacements. It maybe be useful for some applications but in most of the case you'd rather let the FileRepository allocate URIs.
• This version does not enable to get a subresource. It means that if you just want to change an annotation on a document, should shall re-save the whole document. The FileRepository has this functionality.
