This returns an OME::Image::Server::File object, which is documented  
here:
http://openmicroscopy.org/APIdocs/OME/Image/Server/File.html

You can call getSHA1() on it ($frm_file->getSHA1()) along with the  
standard set of I/O calls (open, seek, read, etc).

This returns an object, not a scalar fileID.  The file ID is  
retrieved from the object using $frm_file->getFileID()

This call either succeeds in creating and returning an OriginalFile  
attribute or dies with a "Could not create OriginalFile attribute"  
message.  Are you sure $OF_attr is undefined?  What happens if you  
immediately call:
print "OF ID: ".$OF_attr->id()."\n";

If the above results in an error, then most likely your importer  
class is not properly defined (or the installation is broken, or  
something else serious but easy to fix).  If you post a copy of your  
importer class, we can try to figure out what's wrong with it.
