HOW TO
Because metadata for map services in ArcCatalog is read-only, you may display it, but you may not create, edit, or synchronize it. Any functionality that currently exists for doing this will be disabled. In order to author metadata for map services, you must manually edit metadata and copy it to the appropriate virtual directory on the web server.
c:\Inetpub\wwwroot\Metadata\World.xml
Note:
This file should contain Metadata information for the entire service and Metadata for each individual sub-layer.
c:\Inetpub\wwwroot\Metadata\World_Features.xml
c:\Inetpub\wwwroot\Metadata\World_Features\Countries.xml c:\Inetpub\wwwroot\Metadata\World_Features\Cities.xml
