Jan 1, 2026January 2026 performance for ESA-APEx/apex_algorithms focused on data quality, performance, and governance. Key features delivered include the EFAST definition across SpatioTemporal scales with updated keywords; Sentinel-3 keyword extension to improve searchability; PPI enhancement with updated summary and resource links; a downscaled thumbnail feature to optimize load times and reduce bandwidth; and ACL updates adding admin domains dhi, eodc, and eurac. Major fixes addressed data consistency and processing robustness: a global spelling correction for 'algorithm_provider' across JSON files and notebook MIME type handling improvements with type checks and corrected MIME type. Overall, these changes improve dataset discoverability, user experience, and secure access, while demonstrating strengths in JSON data modeling, catalog governance, and performance optimization.

Nov 1, 2024In 2024-11, delivered a targeted configuration naming consistency improvement for the Advanced Band Combination feature in the ESA-APEx/apex_algorithms repository. The work standardizes the JSON configuration by renaming the internal key from 'offer' to 'order' and renaming the configuration file from advancedbandcombi.json to advanced_band_combination.json. This refactor reduces ambiguity, improves maintainability, and sets a stable foundation for future configuration-driven features. The change was implemented through two commits, providing a clear trace of the refactor: updating advancedbandcombi.json (9f555fe79029cbf840f9c6ad8f910cc840d1df8e) and renaming the file to align with the new naming scheme (f62dcd6681f3f957b2546baa422cf05986388f27).
