Abstract: A workflow schedule authoring tool enables a user to author a workflow by arranging building blocks in a particular order. Building blocks may correspond to events, conditions or actions. Each building block is associated with source code that defines an action to be taken when the building block is processed. The order of the building blocks determines the workflow schedule process. The building blocks allow a user to establish logic conditions for how the tasks in the workflow schedule are executed. A building block may require a user to input parameters before the building block may be executed. The workflow schedule is associated with an event such that the workflow schedule triggers when the event occurs. The building blocks simplify workflow schedule authoring because the user does not need to write any code.

Abstract: A front-end computing system initializes an instance of a workflow. The workflow contains a plurality of activities. The plurality of activities includes a shim activity. When the front-end computing system executes the workflow instance, the front-end computing system performs the shim activity. When the front-end computing system performs the shim activity, the front-end computing system sends a custom activity assembly to a sandbox computing system. The custom activity assembly is not fully trusted. The sandbox computing system executes the custom activity assembly. The sandbox computing system is isolated from the front-end computing system such that unexpected behavior of the sandbox computing system does not cause the front-end computing system to perform unexpected behavior.

Abstract: A server computing system stores at least one workflow template and at least one workflow customization table. The workflow template includes activity elements that indicate activities included in the workflow. The activity elements include attributes associated with input properties of the indicated activities. At least one of the activity elements includes an attribute associated with an input property, the attribute specifying a variable name, not particular data. The workflow customization table includes an entry associating the variable name with particular data. When the server computing system initializes a workflow instance based on the workflow template, the server computing system binds the input property to the particular data specified by the workflow customization table. Thus, by storing different workflow customization tables, the same workflow template can be used to initialize workflow instances having different behavior.
