 == Overview ==
 
-Short description of the improvement proposal.
-... 
+Here is a proposal for harvesting part refactoring. This module is quite old, with a lot of duplicate code (ie. "align" methods). Moreover, the client side is quite complex with lots of Ajax query, XSL transformations on the client side, old javascript librairies used...

- * '''App''': !GeoNetwork or !Intermap

 == Motivations ==
-The current configuration is .... A change to ....
+
+Remove duplicate code.
+Use librairies up to date.
+Store harvesting task into specific model.
 
 == Proposal == 
-An in depth proposal can be found here : link
-...
+
+Both server side and client will be refactored based on an object model and on JSON object. 
+We try to think this new model as generic as it could be in order to be easily extended by any new harvester.
+
+This new model uses specifics tables in the database to store information about harvesters (HarvestingTask, HarvestingTaskResults...).
+
+For now, we did a new interface based on ExtJs only for the OAI PMH harvester and we only move this harvester to the new model, there is some work to move all harvesters and to get them working into the trunk.
