Jun 1, 2025June 2025 (RTX): Delivered a critical data-model fix focusing on attribute type consistency for supporting text. Standardized attribute types to biolink:supporting_text for sentences and publications_info, replacing the previous bts:sentence type and correcting filtering logic. This change directly improves UI retrieval and display of supporting text and reduces edge cases in downstream UI and analytics. Implemented under issue #2499 with a consolidated commit set, enabling traceability and easier future maintenance.
