Data standard

« Back to Glossary Index

Data standard is an agreed upon set of rules that allow information to be shared and processed in a uniform and consistent manner. This includes representations, formats, and definitions of data. Some CDEs have been mapped to existing data standards and vocabularies such as those listed in the Health Information Technology and Health Data Standards at the National Library of Medicine (NLM).
