Tavaxy architecture and interface. Left: Tavaxy Architecture. The authoring module (workflow editor) is where users compose, open, and import workflows into Tavaxy. The imported workflows can be in tSCUFL, SCUFL, t2flow, JSON formats. The mapping module produces tSCUFL files to be executed by the engine. The engine invokes either local tools or remote services. Upper right: The main interface of the Tavaxy system containing links to the authoring module, user’s workflow, user’s data, workflow repository, and other utilities and cloud tools. Lower right: The workflow authoring module, where the switch pattern is depicted. The cloud symbol and the parameter port appear on the tool node. On the righthand panel, the user can choose if a tool runs locally or on the cloud.
