Month: 2025-07 Summary: Delivered a key feature enabling batch tagging for Inspect items in tapdata/tapdata, improving tagging governance and operational efficiency. Implemented API-driven bulk updates via batchUpdateListTags in InspectController, added BatchUpdateParam for input handling, and updated the data model to support tag management by extending InspectDto and InspectEntity with listtags. The work included a refactor of MetadataDefinitionService to map entity classes during batch updates to ensure correct handling across entities. These changes reduce manual tagging effort, enable scalable batch operations, and lay groundwork for governance at scale across Inspect items. Notable commits include messages: - refactor: metadataDefinitionService to use a mapping for entity classes in batch updates and add listtags to InspectDto and InspectEntity. (6da1d0bfb44cc0b411cbf3e400f31fab9bc04075) - feat: add batchUpdateListTags endpoint to InspectController for bulk tag updates (8a9ddf382f47d1d62216ce0a3b56f54b7138d113)
