+# == UUIDResolverController
+#
+# This controller enables applications to retrieve information about a given UUID.
+
+# It can be used to verify the availability of this UUID in the database, e.g.,
+# when a remote Agent assigns an UUID to a record, or when it looks up the
+# record for that UUID.
+#
+# Usually it would either find no matching record (and can thus safely assign
+# the UUID) or a single one (and be redirected to the matching resource.).
+#
+# It's also possible, but unlikely, that the UUID matches more than one record
+# (e.g., a Map and a Resource), given the construction of UUIDs. In that case,
+# the controller will return the list of matching records.
+#
+# === Verifying the availability of an UUID
+#
+# When the call is made to verify an UUID is not yet assigned, a 404 (Not Found)
+# response means the UUID is available.
+#
+# === Identifying an existing record
+#
+# When the call is made to verify the existence of a record matching this UUID,
+# a 302 (Found) response means a single record was found, and the Location
+# header gives its URL. If a GET request was made, then the User-Agent will be
+# redirected to that Location.
