These dates are properties of the nie:InformationElement class, and inherited for its subclasses:\n\n\nnie:informationElementDate: This is an ''abstract'' property that act as superproperty of the other dates. Don't use it directly.\n\nnie:contentLastModified: Modification time of a resource. Usually the mtime of a local file, or information from the server for online resources.\n\nnie:contentCreated: Creation time of the content. If the contents is created by an application, the same application should set the value of this property. Note that this property can be undefined for resources in the filesystem because the creation time is not available in the most common filesystem formats.\n\nnie:contentAccessed: For resources coming from the filesystem, this is the usual access time to the file. For other  kind of resources (online or virtual), the application accessing it should update its value.\n\nnie:lastRefreshed: The time that the content was last refreshed.
