Sep 1, 2025September 2025 (2025-09) monthly summary for molgenis-emx2: Implemented major data-model and data-organization improvements in the patient registry and advanced data integration by merging samples and sequencing runs. Key changes include refactoring Pedigree.csv to use a single ref for relationships (replacing ref_array), updating member/relative field descriptions, and performing CSV and ontology updates to support new Experiment attributes (OGM, RNA, lrGS). Also delivered merged data structures for samples and sequencing runs, along with corresponding model and test updates. These changes improve data clarity, consistency, provenance, and readiness for downstream analytics, while aligning RD3 schemas and strengthening data integrity.
