Okay, so the converters are written in multiple languages, and you 
want them to be able to talk to each other via pipes and across the 
network rather than just through directories.  How to do it?

It seems to me that you could just join the bits of YAML together, but 
you need to somehow know what file each bit belongs in.

for i in `ls examples/flat_db-from_drw2/`
  do cat examples/flat_db-from_drw2/$i
    echo "path: $i"
done > examples/joined1.yml

I'm not sure right now if "path:" is the right attribute to use.  The 
point is that the resultant file can be directly loaded with a YAML 
parser and a secondary process would know how to put it into the 
directory structure.

This opens the conversion scheme to more flexibility and could also be 
used to simplify the connectors.  By having one program that can 
marshall/demarshall between the stream and the directory, the 
connectors could all just write to and read from a stream (unless 
they have something particularly novel to contribute wrt handling the 
directory.)
