Worked on the OHDSI/Vocabulary-v5.0 repository to address a bug affecting Hemonc vocabulary version date extraction. Focused on database development and SQL scripting, the developer updated the SQL logic to accurately parse version dates by targeting the correct HTML span class within the source content. This adjustment ensured that version tracking for the Hemonc vocabulary is now reliable, reducing the risk of downstream mis-versioning and improving data integrity. The solution was implemented and documented in a dedicated commit, reflecting a methodical approach to bug resolution and validation. The work demonstrates attention to detail in SQL-based data extraction and maintenance.
