Thanks for the help. I got the adapter to work as desired, but am
running into some problems with the help phase. It looks like
something has changed since the umql wrapper script was written. I'm
getting the same error as with the relations property:
   http://search.labs.freebase.com/api/service/emql?help=/people/person/relations
Is this not a recommended way of providing help? And are these sorts
of server errors worth reporting via JIRA or is eMQL still changing
too much for it to be worthwhile?
