Mar 1, 2026March 2026 monthly summary for FinOps-Open-Cost-and-Usage-Spec/FOCUS_Spec. Delivered standardization and machine-readable definitions for the FOCUS specification by integrating RM 1.3 enhancements, updating validation schemas, and introducing formal JSON Schemas. Introduced and standardised JSON Schema-based object columns, including the new ContractCommitmentApplicability column, to improve data quality, validation, and interoperability. Established a robust multi-version release approach (releases/X.Y/), and added build_json.py and pytest-based validation workflows to streamline CI checks and conformance testing. Iterated on PDF rendering for code blocks; implemented initial CSS wrapping rules to improve readability, followed by a targeted revert to maintain reliable PDF generation while we pursue a stable long-term solution. Business value: clearer rule authoring, automated validation, and scalable releases across datasets. Key skills demonstrated: JSON Schema design, Requirements Model formalization, versioned tooling, and cross-team collaboration.
