Hi,

Since tool and schedule has an n-to-n relationship (if we think in database concepts :) ), I guess the best way to do is to use metadatas like bellow:
- tool metadata
- schedule metadata
- metadata to join tool and schedule

Now, this might sound silly - but the part I always struggle with is
what 'order' things should be chained:

data -> cron -> owamp
or
data -> owamp -> cron

It probably doesn't matter that much. But, it would be good to have a
clear reason that can give guidance across multiple service/message
definitions. For example, I am hitting a similar issue with bwctl:

data -> bwctl-scheduling -> iperf
or
data -> iperf -> bwctl-scheduling

(This is for a new version of the bwctl schema. The current one
basically has a single metadata that includes iperf and bwctl options.
But the next version of bwctl will support other throughput tools such
as nuttcp and thrulay so I was trying to factor out the bwctl specific
things.)
