The Common Workflow Language (CWL) is a standard for describing computational data-analysis workflows.[1] Development of CWL is focused particularly on serving the data-intensive sciences, such as bioinformatics,[2] medical imaging, astronomy, physics, and chemistry.
Standard
[edit | edit source]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.[3]
The CWL originated from discussions in 2014 between Peter Amstutz, John Chilton, Nebojša Tijanić, and Michael R. Crusoe (at that time their respective affiliations were: Galaxy, Arvados, Seven Bridges, and Michigan State University) at the Open Bioinformatics Foundation BOSC 2014 codefest.
CWL is supported by multiple analysis runners and platforms[4] such as Apache Airflow (via CWL-Airflow [5]), Arvados, Rabix,[6] Cromwell workflow engine, Toil, REANA - Reusable Analyses and CWLEXEC for IBM Spectrum LSF, and was identified in 2017 as one of the future trends for bioinformatics pipeline development.[2] Several additional analysis environments are currently implementing support for CWL including Pegasus[7] and Galaxy.[8]
Availability
[edit | edit source]The CWL Project[9] is a multi-stakeholder working group consisting of both organizations and individuals. A member project of Software Freedom Conservancy, it publishes the CWL standards freely available via its GitHub repository under a permissive Apache License 2.0.
