Nov 1, 2025November 2025 monthly work summary for BioKIC/Symbiota. Key features delivered include a UI enhancement for conditional linking in geographical and taxonomic statistics, which displays links only when child terms exist and adds a data flag to indicate presence of child data, improving UI relevance and interactivity. Major bugs fixed include media loading/deletion issues and permission enforcement for image imports: removal of the option to link new image imports to existing occurrence records via the Taxon Profile Editor (enforcing linking via the occurrence editor for better permission control), refinement of image tid assignment, and server-side image deletion fixes via correct URL-to-path conversion. Additionally, code cleanup was performed to remove an unused language tag from the codebase. Overall impact: improved UI accuracy and interactivity, safer asset and permission management, and better maintainability of the codebase. Technologies/skills demonstrated include UI/UX enhancements, data handling and feature flagging, permission governance, server-side path handling, and PHP code cleanliness.
