Bioimage analysis is evolving to address challenges of big data, dealing with complex modalities like 3D and time-resolved imaging and working towards more FAIR image data and image analysis workflows. A big driver for standardization is the development of the OME Next Generation File Format. As a community, we’re working together towards version 1 of OME-Zarr.

Following up on the successful hackathons in 2023, 2024 (see resulting preprint) & 2025, we are bringing together leading developers and researchers again this fall in Zurich Switzerland. Major topics of the hackathon will be OME-Zarr RFCs, OME-Zarr V1, OME-Zarr viewers, OME-Zarr tooling and OME-Zarr workflows.
