Do you mean a driver that would read (and/or write) ISO 19139 XML files ? Do 
such documents fit (enough) well with the OGR data model ? Is there a concept 
of record/feature ? I'm unfortunately not familiar with what those documents 
look like.

Not sure to understand your need about BAG. There is already a "xml:BAG" 
metadata domain into which the ISO19115 stuff is dumped. So your need would be 
an API to parse the XML ? There are perhaps good ideas in the various projects 
that revolve around CSW.
