October 2025 (2025-10) monthly summary for ONSdigital/dp-dataset-api. Focus: stabilize version handling in putState to prevent publishing with stale version data and to strengthen state transitions. Implemented a fix by introducing a separate versionUpdate object instead of mutating currentVersion. Commit f4d2812221ebd10a9d30418d190ac2e61d1c6a47. Outcome: increased data integrity and reliability of publishDistributionFiles; reduced risk of inconsistent releases. No new features delivered this month; major bug fix focused on correctness and stability.

September 2025 monthly summary focusing on business value and technical outcomes across dp-dataset-api and dp-compose. Key initiatives include stabilizing the dataset publish flow with robust error handling and idempotent state transitions, and introducing a new file_events tracking mechanism in the dataset catalogue provisioning script.

Month: 2025-08 — ONSdigital/dp-dataset-api delivered data integrity and reliability improvements for static dataset versions, strengthening safeguards around edition ID updates and test coverage, while also addressing build stability through dependency harmonization. The changes reduce data corruption risks and regression surface, improve CI feedback, and align test data expectations for consistent release readiness.

July 2025 — ONSdigital/dp-dataset-api Key features delivered: - Dataset Edition Versioning and Edition Link Management: edition-aware version handling; updates edition-specific links when an edition changes; persists edition field and ensures correct linking within the dataset API. - Clarified and enforced behavior for detached version state (set version to nil and remove collectionID) to improve stability and consistency of version state. Major bugs fixed: - Stabilized version state handling by implementing robust rules for detached edition/version states, reducing edge-case inconsistencies when editing datasets with multiple editions. Overall impact and accomplishments: - Improves data integrity and consistency for editioned datasets, enabling safer evolution of dataset definitions and more reliable downstream consumption by clients. - Reduces risk of stale or inconsistent edition links across API responses. Technologies/skills demonstrated: - Edition-aware versioning logic, link management, and persistence patterns in a dataset API. - Code quality and maintainability improvements (lint fixes). Commit references: - c66941b3143eb04809680c69953e57b744c35645 ("update put version") - 99a8e57cd7f44b8ca85aef710b47bb80c0cc62aa ("fix lint")

June 2025 — Delivered Bundle_events Date Handling Improvements in dp-compose. Standardized created_at to ISODate, removed legacy date conversion logic, and refactored date processing to ensure consistent formatting and interpretation across the system. This enhances data integrity for bundle events, improves reliability of analytics, and reduces future maintenance burden across dependent services.

Month: 2025-05. Focused on delivering core data modeling features, seeding baseline data, and tightening data integrity across two repositories. The work improves data reliability for downstream services, accelerates environment setup, and reduces validation friction for static datasets.

April 2025 performance summary: Delivered core dataset access improvements, extended the publish workflow to propagate dataset distributions via the Files API, integrated Files API configuration across services for reliable local and CI environments, and reinforced code quality and error handling. These changes enable programmatic dataset retrieval, ensure published datasets ship their distributions, and simplify local development and deployment. Key outcomes include enhanced data accessibility, automated distribution publishing, and improved cross-service reliability.

March 2025 performance summary for two repositories: dp-dataset-api and dp-compose. Focused on strengthening dataset metadata quality, expanding versioning capabilities, improving code quality, and enabling ecosystem integration. Delivered significant API enhancements, metadata improvements, and a major integration to the dataset catalogue stack via topic API support, underpinned by code hygiene and testing improvements.

January 2025 monthly summary for ONSdigital/dp-dataset-api focused on strengthening data integrity, stability, and maintainability through centralized validation and targeted cleanup. Delivered improvements reduce invalid dataset states and simplify future validation changes while improving test reliability and code hygiene.

December 2024—dp-dataset-api: Delivered a major Theme taxonomy overhaul, API refactor, and expanded test coverage; fixed key Swagger/OpenAPI inconsistencies; and strengthened metadata handling. These changes improve API consistency, data discovery, and overall robustness for downstream systems.

November 2024: dp-dataset-api delivered an API contract cleanup by removing the '@context' field from dataset endpoint responses. This reduces payload size, improves response correctness and performance, and simplifies client contracts. Swagger/OpenAPI and developer documentation were updated to reflect the change, ensuring alignment across APIs and consumers. No new features were introduced this month; the focus was on contract hygiene, documentation, and maintainability.

2024-10 Monthly Summary for ONSdigital/dp-dataset-api: Delivered a new Dataset Creation API (POST /datasets) with input validation, robust error handling, and accompanying tests; updated feature specifications and docs; deprecated the old dataset creation endpoint. Fixed lint-related issue by standardizing the dataset ID error constant ErrMissingDatasetID (previously ErrMissingDatasetId). Swagger/OpenAPI updated to reflect the new endpoint and deprecation; maintained code quality through formatting improvements.
