USCore ModelInfo

Clinical Quality Language (CQL) is a high-level, domain-specific language focused on clinical quality, and it is targeted at measure and decision support artifact authors. Additionally, the CQL specification provides a machine-readable canonical representation called Expression Logical Model (ELM), which is targeted at implementations, and designed to enable automated sharing of clinical knowledge.

To use CQL with USCore, model information must be provided to the implementation environment. The USCore-ModelInfo library provides this information for US Core. To use USCore, include a using declaration as shown in the example below:

using USCore version '3.1.1'
