Do We Need Data Standards in the Era of Large Language Models?

AbstractData standards for the health information ecosystem have played a critical role in enabling software integration across health care enterprises for data sharing, analysis, clinical research, and public health.

Namely, what role do data standards play in the era of large language models, and will we need data standards at all? (Funded by Harvard Medical School.).
