This ontology ("wfdesc") describes an abstract workflow description structure, allowing the description of a scientific workflow as a direct acyclic graph, or a dataflow. This ontology is meant as an upper ontology for more specific workflow definitions, and as a way to express abstract workflows. The wfprov ontology shows how to link these descriptions to a provenance trace of a workflow execution. @en
