Jan 1, 2026January 2026 monthly summary focusing on delivering business value through robust plugin lifecycle support, improved data propagation, and refined content crawling for the LOCKSS daemon. The work centered on the Royal Society Publishing Journals Plugin lifecycle and hosting configuration, AU status propagation, and enhanced crawling/volume handling, with clear naming improvements and post-testing status adjustments. Key outcomes include: - End-to-end lifecycle and hosting configuration for the Royal Society Publishing Journals Plugin, including deprecation handling and metadata updates to ensure safe deployment and hosting controls. - AU status propagation across system code and tdb configuration, facilitating consistent status reporting and easier downstream decision making. - Enhanced article crawling and filtering: extended crawl filters to support jid/year filtering and exclusions of extra articles, improving relevance and reducing noise in indexing. - Volume handling refinements: made volume optional for experiments, enabled volume option for RSP only, and moved the crawl rule to a higher level for better performance and maintainability. - Naming and status hygiene: updated plugin/AU naming for readability and aligned AU status after testing, including adjustments to rsbm Aus to testing where appropriate. Overall impact: Improved reliability and performance of plugin deployment, more accurate status synchronization across components, and tighter control over crawling results, delivering measurable business value in terms of publishing reliability, data quality, and operational efficiency. Technologies/skills demonstrated: plugin lifecycle management, hosting policy configuration, tdb-based status propagation, crawl rule engineering, metadata extraction guard logic, feature/bug lifecycle ownership, and cross-component change coordination.
