Worked on the SUSE/doc-sle repository to implement documentation revision date tracking for all SLES/SLED 15 SP7 chapters. This feature introduced a standardized metadata field using XML, enabling precise version control and clearer historical context across documentation. The approach centralized revision date management, aligning documentation updates with the SP7 release cadence and supporting more accurate diffs for quality assurance and support teams. By focusing on technical writing and documentation best practices, the work laid a foundation for easier audits, streamlined localization, and future enhancements, ensuring that each chapter’s update history is transparent and accessible for ongoing maintenance and review.
