---+ Registry Interface Working Draft Discussion Topic

---++ Should we add a harvestFrom attribute to the VOResource schema?

Both the <nop>STScI registry and Carnivore use an internal atribute called harvestFrom to track where they get records from.  This could be useful to expose when investigating problems in the record contents. 

There is another way to determine a record's origin based on its authority ID which involves searching for the Registry record that claims management of that ID.  However, this is not necessarily the same as where a registry harvested the record from (though it is in practice today).  In addition to addressing this ambiguity, a harvestFrom attribute attached to the record itself is easier to get.  

Since this piece of metadata is not originate from the resource provider, but really describes the registry that manages the record, it would be encoded as an XML attribute of the Resource element.
