+[~] fix exported IRIs
+
+    -> I have various scripts in ulo/ that try to fix the broken IRIs.
+       Most of the IRIs do get fixed, but some I am still very confused
+       about.
+
+    -> Because I already wasted a lot of time on this, I'm going to push
+       forward and have with the data I have. Mean while I sould communicate
+       with whoever wrote the export to get some fixed IRIs.
