+# Normalization steps
+
+This library contains generic logic to normalize (string) data and
+transforms strings to URIs.  It should be applicable to data from
+any source (GenBank, ENA etc).
+
+Important: missing data should be missing or None! Do not fill
+in data by 'guessing'.
+
+When data is malformed a warning should be logged and added to the
+warning list. Functions should be small enough to return only 1
+warning!
