Steering Group minutes 2024/02/22

Date: Thursday, February 22nd, 2024

Topic	Relevant Links and to do
BEP for dimensionality reduction-based networks	Peer Herholz
Avoiding BEP being stuck	Issue with Atlas BEP - circulate the idea of revising BEP development - one point missing in those discussions is how to get unstuck if conflict (CP: item voting is my favourite option, we just need the mechanism for it - like we do to elect this group)
Cooperation with DICOM standard	YOH pointed David Clunie to our DICOMs deficits table , he forwarded to WG-16 to consider at the next meeting.
Updates on plan for website	BIDS Online Presence Working Group: Working Document
BIDS 2.0 going forward!
BEP guidelines updating (Camille & Remi)	https://github.com/bids-standard/bids-extensions/pull/28

BIDS Meeting Notes

Plan for website

• Eric is chairing the BIDS Online Presence Working Group

  • Eric owes the open letter to the Steering Group

• May use google season of docs (need to sign up for the program, starts April 2nd for applications)

  • Will reach out to INCF to reconnect as the admin for google season of docs

  • Mentors identified: Eric, Christine, and Remi (outlined in doc linked in agenda)

• Eric will reach out to the group to schedule a follow up meeting.

• Yaroslav reminded the group that he has $5k CAD to compensate for work on this project

BEP39 for dimensionality reduction-based networks

[https://docs.google.com/presentation/d/1SLvZ7um3RQAiDr6KeK8eO_mNoQ0qHl_bzx_gqIS169Y/edit#slide=id.g152266b1f78_0_45]{.underline}

• May need to introduce new terminology (something akin to an 'index’, param-mixing, param-components, something akin to 'model’)

  • Eric suggests instead of 'index’ potentially like [*_aslcontext.tsv]{.underline}

    • [https://bids-specification.readthedocs.io/en/stable/appendices/arterial-spin-labeling.html#_aslcontexttsv-three-possible-cases]{.underline}

  • <modality>map : discussion determined modality is a suffix

    • Related discussion [https://github.com/bids-standard/bids-2-devel/issues/58#issuecomment-1711758273]{.underline}

  • 'model-ICA_description.json’ : suggestion to rename file as 'dataset_dscription.json’ and include 'DatasetType: model” and model-ICA_mfp.json similarly to 'task-xxx_bold.json

• Current state is to build up and extend 'spatiotemporal decompositions’ introduced in BEP 012

• Interoperability : BIDS-Prov

  • [https://github.com/bids-standard/BEP028_BIDSprov/blob/master/examples/from_parsers/spm/spm_default_batch.jsonld#L65-L77]{.underline}

  • Software parameters is similar to BIDS-prov’s Parameters description (what is the specific file?)

Stalled BEPS

Should there be a mechanism for addressing conflicts that halt BEP progress?

Suggestion: 1. a voting system similar to how the steering group is elected.

How would we want to implement something like this while addressing concerns of FAIRness?

2. BEP leader determines how to move forward.

3. Could a technical committee make these decisions? (maintainers + steering group) - if there is quorum possibility to vote one way or the other

When do we modify the schema to address new ideas?
