# OHBM BIDS Town Hall, June 27th, 2024

Townhall slides: (add link to slides here)

* 2023-2024 Milestones
* openscience prize
* maintainers meeting in Seattle
* publications: Poldrack et al., (2024)
* INCF google season of docs: 
  * weve hired a technical writer 
  * Maintainer mentors.
     
* Organizational Updates
  * looking for 1 new steering group member to replace Ariel Rokem's position
  * New Working Groups: 
    * Online presence (*Eric Earl*)
    * Governance (*Ariel Rokem*)
    * BIDS2.0 (*Yaroslav Halchenko*)

* Technical Updates
  * New BIDS validator releases based on BIDS schema
  * BIDS schema group meets every Thursday, new contributors welcome!

* BEPorama
  *  Current BEPs are listed on BIDS website
  *  New BEPS: 
        *  BEP041: Statistical Model (*Taylor Salo*)
        *  BEP042: Electromyography (*Yahya Shirazi*)
        *  BEP043: Term mapping (*Chris M*)
    * Ongoing BEP review summary
    * potential BEP: stimuli (to be formally established)
    * potential BEP: "Peripheral" physiological signals
    * BIDS Connectivity Project Updates
        * 7 BEPS
        * **lessons learned:** there is no procedure for addressing and resolving BEP feedback, establishing a timeline would help to continue progress
        * **Suggestions**:  clarify roles and responsibilites of BEP leads, define timelines for BEP tasks

* BIDS 2.0 (*Yaroslav Halchenko*)
    * Goal: Make BIDS better :) 
    * Now an official Working group
    * Will provide a migration script to update BIDS 1.0  to BIDS 2.0
    * [BIDS 2.0 github](https://github.com/bids-standard/bids-2-devel/issues)
    * Join the effort! 

* The BIDS Community (*Christine Rogers*)
    * We need help with some BEPS, please reach out to leads
    * BIDS Datasets in Open Neuro appear to show reasonable global interest
    * BIDS DIversity
        * Gender representation 2:1 male/female
        * BIDS Community Survey Results (n=128)
        * New website in development: https://bids-website.readthedocs.io
    * outreach goals: 
        * new users
        * convert users to contributors
        * Areas of Growth: inclusivity, barriers to adoption, etc

BIDS contributors Please update affiliations! 

**COMMUNITY INPUT AND DISCUSSION**
App Questions: 
Q: How can I get started to contribute to BEPS?
A: BEP lead info is listed on the BEP docs

Q: Aggregating datasets is a challenge. How can BIDS support this? 
A: BEP35. [Neurobagel](https://neurobagel.org/) also has some potential solutions. 


Q: BIDS 2.0. What is the timeline for that and what happens with tools that support 1.0?
A: Hopefully, it wouldn't break things to badly, especially if the core dependencies (i.e., pybids and similar). 

Q: Clinicians want to share data, but it's overwhelming to get into BIDS, and clinicians don't have time. Can that be made more easy by providing ???.  

Q: Lesion masks ergo? 
A: Right now, it needs to go to the derivatives. 

Q: How should we deal with multiple descriptions? Sometimes that's multiplicative. 
A: Combine them with some character such as a "+" (which you can use ;-)), but multipled `desc` entities is not happening anytime soon. 

Q: Dylan Nielson: Is there a tool or under development for editing BIDS trees (e.g., remove a subject or a scan and all of its outcomes)
A: Looks like the asker is already making it. 

More a comment than a question: Chris G is here!  

Q: Proposed to establish a BIDS Working Group in China. This will be useful in some unique settings and projects that require standardization. E.g., massive traveling brain projects. Language is a big barrier and there are cultural barriers as well. 

Q: We need a roadmap. 
A: Yes, we do. But the community-driven nature of the project makes this rather compicated. For example, a graduate student working on a BEP might graduate and move on and then development might stop.
