Category Standard

Great Expectations is a verified, industry-standard open-source framework for data quality with significant verifiable traction (3M+ monthly downloads, ~$64.5M funding, and wide enterprise adoption). However, the project submission itself was of extremely low quality, containing hyperbolic claims ('everyone', 'most people'), incorrect tags ('Apparel & Fashion'), and lazy data entry. The high score reflects the immense real-world utility and established market dominance of the software, adjusted downward for the lack of professional detail in the application.
