Is ESRI metadata standard compatible with GeoNetwork metadata standard? if yes how do i update the Geonetwork metadata using Arc-Catalogue 10 Metadata xml?
You may have an easier time using the FGDC metadata editor which was available at previous releases of ArcGIS Desktop. There is an add-in that will make this possible. Here is a link to ESRI's blog post about the topic: http://goo.gl/TlhdS
