+      A related issue ariese when querying labeled extracts and joining
+      the source events collection to use the linked hybridizations in

+ItemQuery<LabeledExtract> labeledExtractQuery = LabeledExtract.getQuery();

+// This no longer works

+
+// Replace the above line with these two line

+      The good new is that the modifcations makes it possible to filter

+      to get more information.
