PROFILE
Jan Funke
During their work on the live-image-tracking-tools/geff repository, Funke focused on building robust data persistence and spatial graph IO capabilities for graph pipelines. They implemented Zarr-based and spatial graph IO, enabling efficient reading and writing of graph data, including metadata and node or edge attributes, while ensuring data integrity through schema validation and dtype consistency. Funke integrated the spatial_graph dependency, refactored IO helpers for selective loading, and extended the GEFF schema with display hints for spatiotemporal axes. Using Python, YAML, and Numpy, their contributions improved build reproducibility, repository hygiene, and visualization control, resulting in more reliable and maintainable data pipelines.

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.
