The Common Workflow Language (CWL) is a specification for describing analysisworkflows and tools in a way that makes them portable and scalable across a
variety of software and hardware environments, from workstations to cluster,cloud, and high performance computing (HPC) environments. CWL is designed tomeet the needs of data-intensive science, such as Bioinformatics, MedicalImaging, Astronomy, Physics, and Chemistry.

CWL is developed by a multi-vendor working group consisting oforganizations and individuals aiming to enable scientists to share dataanalysis workflows.The CWL project is maintained onGithuband we follow theOpen-Stand.org principles for collaborative open standards development.Legally, CWL is a member project ofSoftware Freedom Conservancyand is formally managed by the electedCWL leadership team,however every-day project decisions are made by theCWL communitywhich is open for participation by anyone.

CWL builds on technologies such asJSON-LDfor data modeling andDocker for portable runtimeenvironments.

TheCWL user guide provides agentle introduction to learning how to write CWL command line tool and workflowdescriptions.
