Version 3 Schematron
This page contains information about Schematron, which is used in the NEMSIS Version 3 Data Standard to achieve better quality by enforcing business rules and other constraints that cannot be enforced in the NEMSIS XML Shemas
Schematron is a rule-based language for XML document validation. Schematron is an international standard defined in ISO/IEC 19757-3(2006).
Version 3 National Schematron Rules were developed in plain english through a consensus process by the NASEMSO Data Manager Council (DMC). The DMC membership was interested in an initial set of national rules designed to help assist EMS agencies across the nation document the national elements appropriately based primarily on good judgement and some clincial decision making. Using the plain english rules, NEMSIS TAC developed pattern-based national Schematron rules which were first published in 2014.
The latest update to the national Schematron rules was released on June 7, 2019. See the NEMSIS Schematron Change Log for details.
