This page contains information about the NEMSIS Version 3 Data Standard for mapping or translating older versions of the dataset to newer version of the dataset. The XSLT tools for data translation between NEMSIS standard versions have been developed by the NEMSIS Technical Assistance Center for the primary purpose of translating data for the research dataset. These tools are provided for informational use and are not recommended for widespread use in data collection systems such as agency-to-state-to-national data collection flow. Degradation of data quality in this scenario can be significant.
