The Common Workflow Language (CWL) is a specification  for describing computational data-analysis workflows. Development of CWL is focussed particularly on serving the data-intensive sciences, such as Bioinformatics, Medical Imaging, Astronomy, Physics, and Chemistry. A key goal of the CWL is to allow the creation of a workflow that is portable and thus may be run reproducibly in different computational environments.
The CWL originated from discussions in 2014 between Peter Amstutz, John Chilton, Nebojsa Tijanic, and Michael R. Crusoe (of Galaxy, Arvados, and Seven Bridges) at the Open Bioinformatics Foundation BOSC 2014 codefest.
CWL is supported by multiple analysis environments such as Apache Airflow (via CWL-Airflow ), Arvados, Rabix, and Toil, and was identified in 2017 as one of the future trends for bioinformatics pipeline development. Several additional analysis environments are currently implementing support for CWL: Apache Taverna, Cromwell workflow engine, Galaxy, and REANA - Reusable Analyses.
