Where can I find an overview of current or future-planned CQL execution tooling, i.e., Structured Query Language execution, or Extensible Markup Language (XML) execution engines?

To learn about current Clinical Quality Language (CQL) execution tooling, review the CQL GitHub tooling repository, which includes the CQL-to-ELM translator, execution engines, and related implementation tools. You can also review the eCQI Resource Center's CQL Execution Framework page and the CQL specification's Reference Implementations documentation for information about available execution frameworks and supporting tools. Available tooling includes open-source ELM evaluation engines for JavaScript and Java, as well as a .NET toolkit that supports ELM translation and evaluation.
