Abstract: Techniques are provided for versioning and refactoring of mashups. During the design phase of a mashup that is operable to access multiple external services, design information that defines or modifies a plurality of design elements included in the mashup is received from a user. Without receiving from the user any input that causes the plurality of design elements to be versioned, current versions of the plurality of design elements are automatically stored in a repository when the plurality of design elements are saved during development of the mashup. The mashup is deployed to one or more servers. Without receiving any input from the user that causes the mashup to be versioned, deploying the mashup comprises automatically storing in the repository a current version of the mashup and versioning information that associates the current version of the mashup with the current versions of the plurality of design elements.

Abstract: Techniques are provided for designing, deploying, and executing mashups that integrate human workflows with automated processes. In an example embodiment, a system for executing mashups comprises a human interaction module, an event manager module, and a process orchestration module. The human interaction module is configured to receive user input while a human workflow included in a mashup is being executed, and to raise an event in response to the user input. The event manager module is configured to: receive the event from the human interaction module; based on the event, identify a particular automated process from one or more automated processes that are included in the mashup; and invoke the process orchestration module to execute the particular automated process based on the event. The process orchestration module is configured to execute the particular automated process in response to being invoked by the event manager module.
