+BIDS permits structured citation files that may improve interoperability with
+dataset indexing utilities or afford higher precision than fields in
+`dataset_description.json`.
+
+If these files are used, fields that provide information that is redundant with
+`dataset_description.json` fields SHOULD be preferred to those in `dataset_description.json`.
+
+To avoid inconsistency, metadata present in one of the following files SHOULD NOT be
+be included in `dataset_description.json`, with the exception of `Name` and
+`DatasetDOI`, to ensure that tools that are only aware of `dataset_description.json`
+can generate references to the dataset.
+
+In particular, if a structured citation file is present,
+the `"Authors"` field of `dataset_description.json` MUST be omitted.
