Kyosuke Miyachi developed and modernized document content extraction and indexing workflows for the RCOSDP/weko repository over a three-month period. He implemented PDF text extraction pipelines, initially integrating Apache Tika with Docker Compose and later migrating to pypdfium2 for improved reliability and broader document-type support. His work included containerizing Tika within Docker images, establishing reproducible build processes, and refactoring file I/O logic using Python and YAML. By introducing a dedicated reindex command and automating task management, Kyosuke enhanced indexing efficiency and maintainability. The engineering depth is reflected in robust dependency management, scalable deployment, and test-driven development practices throughout the project.

Jan 1, 2025January 2025 (Month: 2025-01) RCOSDP/weko work focused on enabling reliable PDF content extraction and searchable indexing via Apache Tika, with Docker Compose integration. Delivered a Tika-based extraction and indexing workflow and prepared the deployment environment for scalable ingestion by running Tika in a JAR and updating Docker Compose for both main and secondary services. Added a test PDF to validate end-to-end functionality and indexing readiness. No major bugs were reported this month. Overall impact centers on improved document searchability, deployment consistency, and a foundation for future ingestion pipelines.
