[GeoNetwork-users] Harvesting ESRI Metadata

I'm trying to figure out what the best way is to harvest metadata created in ArcGIS into GeoNetwork. I have created a shapefile and updated the metadata in ArcGIS, then used the harvesting in GeoNetwork to bring the information into GeoNetwork. The harvesting job runs successfully and adds the shapefile layer but I do not see any of the information created in ArcGIS being added, for example in ArcGIS I update the Summary information but it does not show up in GeoNetwork. I've tried a couple of different metadata formats but have had no success. Is there any way to get this to work?

Thanks
