PROFILE
Jan Funke
During two months on the live-image-tracking-tools/geff repository, Funke focused on building robust graph data persistence and spatial graph IO capabilities. He implemented Zarr-based read and write functionality for graph metadata, node and edge attributes, and IDs, ensuring reliable data serialization and validation using Python and Numpy. Funke also enhanced schema definition by adding display hints for spatiotemporal axes, improving downstream visualization. His work addressed environment consistency through dependency management and reproducible builds, while a targeted bug fix enforced dtype consistency for node and edge IDs. These contributions strengthened data pipelines, improved onboarding, and enabled more reliable analytics and visualization workflows.

Jul 1, 2025July 2025 monthly summary: Delivered robust Spatial Graph IO capabilities and schema enhancements for geff in live-image-tracking-tools, resulting in more reliable data ingestion/export, improved visualization control, and stronger data integrity. The month focused on implementing Spatial Graph IO (read_sg/write_sg), integrating the spatial_graph dependency with refactored IO helpers and selective loading (node_props/edge_props), extending GEFF schema with display_hints for spatiotemporal axes, and fixing a critical bug to ensure node and edge IDs have matching dtypes when writing graph data. These changes strengthen data pipelines, improve performance through selective loading, and provide clearer, schema-driven visualization for stakeholders.
