NGFF PRs

Infra:

• bump dev submodule ome/ngff#448
• fix: move dependabot config to correct location ome/ngff#449
• reactivate review action ome/ngff#440 (needs small changes)
• fix: update Dependabot path for gitsubmodule (#452) ome/ngff#453 (ready)

RFCs:

• RFC 4: review from David Horsfall/ Hannifa lab ome/ngff#435 is a review with discussion... but probably should be just merged as it comes from external.
• Add RFC-5 comment 4 ome/ngff#445 a comment on RFC 5

Docs:

• Improved .mailmap ome/ngff#443 (needs small changes)
• More help for contributing ome/ngff#439 (small changes, but ok to go)
• Add RFC process document (#369) + mermaid dependencies ome/ngff#427 (should be ok to go)
• Improved .mailmap ome/ngff#443 (small changes, close to ok)

Legacy PRs: What to do?

Suggestion: close with comment. If still needed, open a new ticket with someone assigned. Discussions will be present in the history anyways.

• Coordinate transforms json-schema (request for feedback) ome/ngff#149
• Proposal: Add UUID field to multiscale objects ome/ngff#115
• Propose resolution _groups_ for xarray support ome/ngff#114
• simplify multiscale and examples ome/ngff#172

If changes still relevant, they need porting to ngff-spec.

Somewhat active PRs that are in NGFF but would need porting to ngff-spec:

• Generalize well organization in high-content screening: field of view => image  ome/ngff#137
• Resolving misc issues and ambiguities in labels section ome/ngff#170
• Require same datatype for all arrays in multiscales:datasets ome/ngff#154 (little lines of changes, seems ovewhelmingly accepted)
• Rename latest schema documents ome/ngff#237 (port + draft, including figuring out redirects)
• Add CITATION.cff ome/ngff#175 could be closed in favour of Add authors to project metadata ome/ngff-spec#31

NGFF-SPEC

• Relax the allowed names of images in wells ome/ngff-spec#71 approved, but 3 approvers don't have write permissions (will-moore, thewtex, imagejan).
• Update strict_well.schema ome/ngff-spec#86 ready
• Add authors to project metadata ome/ngff-spec#31 is dragging for a long time. Need decision on the course of action here (maybe Editorial Board (aka Josh)-level?)
• By dimension input axes number ome/ngff-spec#97 (ready)

PRs with conflicts:

• Fix multiscale examples ome/ngff-spec#24 (simple, quick-ish)
• Mandate that axis field names are strings ome/ngff-spec#60 (simple, quick-ish)
• markdown style fixes and correct links ome/ngff-spec#88 (approved, but conflicting)
• Add copyright note ome/ngff-spec#29 license change... move to draft?

PRs with pending changes:

• omero fields optional ome/ngff-spec#87 is waiting for Omero metadata optional will-moore/ngff-spec#2

PRs needing initial reviews:

• Make image label key mandatory for label images ome/ngff-spec#89
• No separate field for array coordinate system ome/ngff-spec#90 (also, codespell checks failing)
