Hi Marten,
Thanks for the reply. Yes, I am logging using Geoportal username&password and publishing it from ArcCatalog. I've created a metadata file using "Export Metadata" option for a particular dataset and tested whether Publish client tool is able to publish the metadata to Geoportal site or not. It�??s working properly and after approving the posted resource in Geoportal it is coming inside the search page.
But when I use metadata editor from ArcCatalog (UK Gemini) to create a metadata file, it is creating the metadata and also able to save without any error, when I point this file while publishing to geoportal, it is giving me the error.
I am not sure where I am doing wrong while creating metadata file using editor in ArcCatalog.
Thanks and Regards,
