Nov 1, 2025November 2025 monthly summary for the ddbj/www repository. Focused on improving submission quality and clarity through documentation enhancements and a policy-driven workflow update. Key changes include: (1) Documentation improvements clarifying the optional nature of quality metrics for MAG assemblies and providing enhanced guidance for spatial gene expression data submissions, and (2) a workflow refactor that removes deprecated data types by deleting tpa-inf and tpa-exp functionality and stopping acceptance of new submissions for TPA:experimental and TPA:inferential data types, clarifying the process for submitting third-party nucleotide sequence data. Impact: reduced submission ambiguity, lower risk of invalid data types, and faster triage and processing of valid submissions. Technologies/skills demonstrated: documentation discipline, backend workflow refactor and policy enforcement, version-control hygiene, data-domain knowledge for MAG submissions, and cross-functional coordination with data governance. Business value: improved data quality, compliance, and onboarding efficiency for submitters and reviewers.
