Jan 1, 2025January 2025 performance: Delivered end-to-end readiness for 2025 content cycles and platform modernization in lockss-daemon. Key actions include hardening the release pipeline with comprehensive readiness checks and volume testing, updating 2024→2025 buckets across core data structures, and expanding metadata with new titles, embargo notes, and manifest-page verification. Platform modernization progressed with OECD TDB retirement, AAI moved to OUP, and groundwork for Ubuiqity conversion, complemented by mothballing of legacy items. Ingest and testing improvements increased crawl reliability and coverage for new AUs, with broader data-quality cleanup across back content and incomplete-year supersessions.
