Developed a new Commodity Product Grades Enumeration within the rosetta-models/common-domain-model repository, standardizing the representation of oil and gasoline product grades. This work involved data modeling and the use of a domain specific language to define and map product grade values to FpML standards, ensuring consistent data interchange across systems. By aligning the Common Domain Model with industry-standard mappings, the implementation established a foundation for more accurate downstream analytics, pricing, and risk assessment. The approach focused on harmonizing commodity product characteristics, enabling improved reporting and processing capabilities for commodity data within the broader Rosetta modeling ecosystem. No bugs were reported.
