ECL (Expression Constraint Language) Implementations

The Expression Constraint Language is a fundamental component of the data analytics process, converting clinical requirements into computable queries that select a set of concepts with a specific meaning. Some examples of implementations, which support the SNOMED CT Expression Constraint Language include:

• Snowstorm (SNOMED International's Terminology Server) - https://github.com/IHTSDO/snowstorm
  • Provides API for the SNOMED International public browser (See "Expression Constraint Queries" tab) - https://browser.ihtsdotools.org/
• CSIRO Ontoserver Expression Constraints - https://ontoserver.csiro.au/shrimp/ecl.html (help)
