Nov 1, 2025November 2025 monthly summary for wellcomecollection/catalogue-pipeline: Focused on code organization refactor of license override related functions to improve maintainability without altering behavior. Delivered a targeted reorganization by moving set_license_override and remove_license_override to the end of miro_updates.py after image suppression/unsuppression logic. This change, captured in commit d9c21dbd9a895bcfe3c75ab970640a7036bed284 ('move things around'), enhances logical grouping and reduces cognitive load for future changes. No major bug fixes were recorded this month for this repo; primary impact is maintainability and readiness for future feature work.

Oct 1, 2025October 2025 monthly summary focused on delivering richer visual context and strengthening data governance within the wellcomecollection/catalogue-pipeline. Key work included implementing Concept Image Display and Overrides for multi-image support and display_image_url handling, with updates to the concept override provider and tests/labels to align with new visual concepts. Additionally, Miro image tooling was enhanced with dry-run capability, license overrides, and a data-dump view to improve validation, compliance, and data integrity. Testing quality and documentation were improved through standardized naming (camelCase), corrected test names, and updated weco-authority sourceLabel handling for overridden descriptions. Location labeling and test formats were standardized to ensure consistency across image-related concepts, reducing rollout risk and improving maintainability.

Sep 1, 2025September 2025: Delivered a set of data-graph and pipeline improvements for the catalogue-pipeline, with a focus on business value, data quality, and maintainability. Implemented graph edge modeling enhancements (HAS_INDUSTRY, HAS_FOUNDER) and a new SourceConceptHasFieldOfActivity edge, unified FIELD_OF_WORK, and introduced streaming of founder edges across node types, improving query accuracy and downstream analytics. Expanded test data and coverage for founders, fields of activity, and wikidata/LOC edge relationships, ensuring reliability for production indexing. Conducted infrastructure cleanup and security hardening by removing deprecated Terraform config and extending S3 IAM policies to include s3:ListBucket. Added time-aware ontology checks via pipeline_date to improve data relevance over time. Also performed targeted code maintenance and refactoring to improve readability and maintainability.

Aug 1, 2025August 2025 — Wellcome Collection catalogue-pipeline: focus on reliability, throughput, and maintainability of the data ingestion pipeline through targeted feature delivery, major bug fixes, and infra refinements that deliver measurable business value. Key features delivered: - EBSCO adapter and S3 handling improvements: enhanced trigger path, most-recent S3 file selection, decrypting parameters, and trimming EBSCO response before filename validation; added more realistic tests with mocked S3 data; introduced tracking of processed records. - Loader Lambda capacity and permissions enhancements: increased memory allocation and updated IAM/permissions to support higher load and secure operation. - Transition and runtime logic improvements: refactored transition trigger to loader and refined handling of concept types and subject mappings for more robust state transitions. - S3 data lifecycle policy and infra refinements: introduced S3 data handling improvements, lifecycle policy updates, and Terraform/config cleanups to simplify and stabilize deployments. - Code quality and consistency enhancements: broad linting/typing improvements, formatting cleanups, and test adjustments to improve maintainability and reduce CI issues. Major bugs fixed: - Transition and runtime fixups: corrected Choice state checks, sequencing of TransitionStep/TriggerStep, ensured successful end states, and validated single-concept assumptions. - CI and code-review fixes: resolved CI/check failures, addressed code review comments, and completed formatting/refactor passes to satisfy CRs. - Infra and config sanity: removed unnecessary remote state and performed targeted infra cleanups to reduce deployment friction. Overall impact and accomplishments: - Higher data ingestion reliability and traceability with better end-to-end processing visibility and test coverage. - Increased processing throughput and stability under peak loads due to Loader Lambda enhancements and tighter runtime logic. - Lower maintenance burden through code quality improvements, clearer type handling, and consolidated business logic. Technologies/skills demonstrated: - AWS: S3, Lambda, IAM, and lifecycle policies; Terraform/infra adjustments. - Python: typing, linting, test doubles, and refactoring patterns. - CI/CD: lint/test automation, checks, and code review discipline. - Data quality and observability: end-to-end tracking of processed records and test-driven validation.
