What's the difference between `session_description` vs `general/experiment_description`

[ehennestad]

The docs are very minimal:
session_description (required): "A description of the experimental session and data in the file."
general/experiment_description (optional): "General description of the experiment."

My initial guess is that the experiment_description is a broad term that describes an experiment as a whole, where that experiment can include multiple sessions and different protocols. So it would be the same across multiple NWB files, whereas the session_description could be different for different sessions.

However, an experiment is a very broad term, and it is not defined here. It can be used at many levels, from a "collection of sessions" down to a "single measurement under a particular protocol".

This should be clarified, ideally with examples.

That is my understanding as well. I.e., the NWB file represents the session so session_description describes that and the experiment_description provides broader context of the experiment that the session is part of.

Just to clarify, the proposed resolution to the issue is to enhance the doc in the schema for experiment_description?

Yes, and clearly state how it differs from session_description
