    - Done: fixed merge conflicts with branch (6 years old)
    - Now: script to create OMERO.table
    - Then: update views.py code to use OMERO.table to load shapes per region



11th March 2025.

Attending: Will, Andreas, J-M, Petr

- Will iviewer PR https://github.com/ome/omero-iviewer/pull/465 JM: need to look at the bigger picture. How to handle location-based loading of ROIs?
- Will: Use cases doc created at https://docs.google.com/document/d/16vo0J_T6uy7zWPsu0lQz1VaSRqLjtH5CDGoasCjxMrk/edit?tab=t.0 
- Will: Options are PostGIS (not likely) and OMERO.tables (see https://github.com/ome/omero-figure/issues/569)
- Will: Previous iviewer PR to use Vectortile for loading Shapes for tiles https://github.com/ome/omero-iviewer/pull/227. Could try to use OMERO.table at the backend for location based queries? JM: OK.

25th Feb: 11:00.

Attending: Will, Andreas, JM, Petr, 

- I created an issue for lots of Channels: https://github.com/ome/omero-figure/issues/624
- We have https://github.com/ome/omero-figure/issues/569 for the adding ROIs issue. Still needs more thought
- Iviewer "Save as figure" PR is https://github.com/ome/omero-iviewer/pull/465. What other viewers are we thinking of?

- The figure file format is described at https://github.com/ome/omero-figure/blob/master/docs/figure_file_format.rst which specifies the required and optional fields etc. We could formalise that a bit more, with MUST, MAY etc as at https://ngff.openmicroscopy.org/0.4/index.html but I am not sure that it will be worth creating JSON schema files for validation etc. 

- Big Zarr https://github.com/ome/omero-figure/issues/625 


- TODOs:
    - describe workflows for working with big images & ROIs
    - What can I load when? Backend support?
    - Spec for grouping channels
    - OME-Zarr labels support in figure?
    - Do we think about implementing ROI Folders support in web?
    - First support adding many Shapes to ROI in iviewer!
    - Where to describe workflows? Internal gdoc. Can share on gh when 'ready' EDIT: [created gdoc](https://docs.google.com/document/d/16vo0J_T6uy7zWPsu0lQz1VaSRqLjtH5CDGoasCjxMrk/edit?tab=t.0)
    - Meeting again same time next week EDIT: (2 weeks).
