Jason,

I suspect that the metadata system they are putting in is more in the  
line of free-form storage system associated with a resource rather  
than a structured metadata standard (FGDC?) which you seem to think  
this is.  I could be wrong :)

For instance, the description of the MapDefinition that you enter in  
Studio is stored in a metadata tag inside the actual XML  
representation of the MapDefinition.

I think you raise an excellent point, though.  It could be very  
compelling to have a real metadata capability inside MapGuide.

Cheers

Paul
