 Most core principles of the original BIDS and particulars of BIDS-iEEG specification are adopted

+Unprocessed microelectrode electrophysiology (`icephys` and `ecephys` modalities) data must be stored in an [open file format](https://en.wikipedia.org/wiki/Open_format),
 while the native format, if different, can be stored in an optional  `sourcedata/` directory.
-The native file format is used in case conversion elicits the loss of crucial metadata specific to manufacturers and specific `cephys` systems.
