Convergence between DANDI Layout and BIDS

**Ultimate goal**: abandon ad-hoc DANDI layout and thus benefit from all BIDS goodness!

**Compromise goal**: we arrive at BIDS-based (patched BIDS schema) standard.

**The approach**: bring what is good in DANDI to BIDS to make BIDS more convenient for researchers working in DANDI supported fields of neuroscience.

## Major aspects

- BEP032 (https://bids.neuroimaging.io/bep032) as to provide general support for microelectrode electrophys in BIDS
- https://github.com/bids-standard/bids-2-devel/issues/54
- TODO: find it. Allow in BIDS more composite "labels" so we could have `-` or at least `+` in the label within the filename
- BIDS filename suffixes in DANDI might need to be changed
- we would need to be able to ensure that BIDS metadata is non-ambigously maps into dandi-schema. Known issues:
- https://github.com/bids-standard/bids-2-devel/issues/82
...

## Left-over aspects

which unlikely to be resolved in BIDS and need more thinking on how to resolve to become properly BIDS compliant:

- ATM we use composite suffixes suchas `_behavior+ecephys` whenever nwb contains multiple data types. TODO: decide on what to do about that. May be could be resolved via:

## Ongoing activities

- development of https://github.com/con/nwb2bids
