Description: Subsequent downloads with the same predicate as a previous one should reuse already created results within a certain timeframe like a day or week at least. In particular for larger downloads of the entire index, whole kingdoms or datasets this is very useful.

Implementation wise we need to add a new oozie job property telling about a previous downloadId that already has the results for that predicate. ]]>
