+# 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!
+#
+#   Pjotr Prins (c) 2021
