+# the myslice chaps rightfully complained about the following discrepancy
+# they found that
+# * read operations (resolve) expose stuff like e.g.
+# 'reg-researchers', or 'reg-pis', but that
+# * write operations (register, update) need e.g.
+# 'researcher' or 'pi' to be set - reg-* are just ignored
+#
+# the '_normalize_input' helper functions below aim at ironing this out
+# however in order to break as few code as possible we essentially make sure that *both* fields are set
+# upon entering the write methods (so again register and update) for legacy, as some driver code
+# might depend on the presence of, say, 'researcher'
+
+# normalize an input record to a write method - register or update
+# e.g. registry calls this 'reg-researchers'
+# while some drivers call this 'researcher'
+# we need to make sure that both keys appear and are the same
