During September 2025, this developer expanded taxonomy source support within the rosetta-models/common-domain-model repository by implementing a new enumeration value, ‘CFTC’, in the TaxonomySourceEnum. Focusing on data modeling and enum definition using Rosetta, the enhancement broadened the range of supported taxonomy sources, directly improving data ingestion and categorization processes. The work was scoped to a single feature with a clear commit history and did not involve bug fixes during the period. By refining the asset common domain model, the developer contributed to stronger data quality and more robust downstream processing for taxonomy-related data within the existing data pipeline.
