	~~==== Sugar Network layers ====~~

	This is an attempt to generalize the idea of [http://groups.google.com/group/sugar-network/browse_thread/thread/4cad05ec801f364c user/resource levels] with idea that objects should not be removed from the Network immediately (only hidden, and permanently removed by Network administrators). So, every resource is associated with a layer, i.e., it might be visible for observers only if they requested this layer and have permissions to see it.

	~~For now, implemented only the following list of layers, but it might be reused for [http://groups.google.com/group/sugar-network/msg/f5a1b4d78494a5d3 teachers related workflows] later:~~

	* {{Code\|general}}, the default layer for observers and Network objects; all users can see objects on this layer;
	* {{Code\|deleted}}, Network objects' layer will be changed to {{Code\|deleted}} after removing objects by users.

	~~==== Events types ====~~

	* {{Code\|create}}<br>object was created;
	* {{Code\|update}}<br>object's properties were modified;
	* {{Code\|delete}}<br>object was deleted (hidden);
	* {{Code\|vote}}<br>object was voted/unvoted.

	~~==== Licences ====~~

	~~Short license names. The licenses should conform with the [[Activity Library]] licensing [[Activity_Library/Editors/Policy/Licensing\|policy]].~~
