We are a home for Earth science data and computing professionals. Our sessions bring together the community for hands-on, interdisciplinary deep dives as we explore "Bridging Divides: Data, Technology, Community" this year. Learn more about this theme on the ESIP Meetings page.
Session and plenary recordings will be published on the ESIP YouTube Channel.
The NetCDF-CF based Unidata Common Data Model has become the de facto abstract data model for interchange of cell-based spatiotemporal data, but related conventions are being substantially renegotiated. Zarr v3 was released in early 2025 with sharding and a formal extension mechanism designed for community members to contribute Zarr extensions. The Zarr community prototyped a modular Zarr Conventions framework at the October 2025 Zarr Summit. In recent years, STAC became an OGC Community Standard and there is active work on aligning the datacube extension with the bands construct in the STAC core. OGC API-EDR is developing rapidly and aims to provide a set of use-focused query interfaces to data collections in this space. This session will bring together community members who work across these projects to discuss convergence, divergence, and coordination needs. The deliverable is a public seminar series proposal and specific actions.
Agenda: - Ethan will give background and status of the Unidata Common Data Model and NetCDF - Dave will describe current workrelated to Zarr, STAC, and OGC-API - Max will present the status and plans for GeoZARR - We will open the floor to discuss needed next steps to harmonize and coordinate the various efforts in the space.
Audience Data managers, cloud native specialists, oceanographic/atmospheric/landscape modelers, software developers, data modelers working with Zarr, NetCDF, STAC, CF, or OGC standards
