WorkflowHub is a registry for describing, sharing and publishing scientific computational workflows. WorkflowHub aims to facilitate discovery and re-use of workflows in an accessible and interoperable way. This is achieved through extensive use of open standards and tools, including Common Workflow Language (CWL), RO-Crate, BioSchemas and Tool Registry Service (TRS). This FAIR workflow registry is sponsored by the European RI Cluster EOSC-Life and the European Research Infrastructure ELIXIR.
