    • The Taverna workbench to design and run workflows
      • UI plugins for each service type
      • executes workflows using the Taverna platform API
    • The Taverna command line which executes workflows using the Taverna platform API
  • A Taverna Server, which exposes the Taverna platform API as a REST API and SOAP API for executing workflows
