Tools (5)

search_measures239 tok
Find measure packages by CMS id, title words, steward or package id. Every word must match. Shared CQL libraries are packages too; pass kind "library" to search them.
known_issues173 tok
Interpretation issues, defects, test cases and implementation notes, with their full text. Read these before writing or reviewing measure logic.
get_bundle120 tok
The package as a CRMI artifact Bundle, the shape CRMI's $package returns: an asset-collection Library, then the Measure, its Library and every shared library it depends on.
get_measure118 tok
A package: title, steward, license, provenance (upstream commit, unmodified or derived, and exactly what changed), value set references, file list and known issue summaries.
get_artifact97 tok
The raw text of one file a package lists: CQL, SQL, a ViewDefinition, or a FHIR Measure.
