WORKFLOW EXECUTION MODEL

摘要

Embodiments are directed to implementing a generalized workflow execution model configured to provide access to workflow elements. A computer system instantiates a generalized workflow execution model that provides access to workflow elements stored in a database that is connected to the workflow execution model. The workflow execution model includes the following: activity models that include both agents which are configured to express the control flow of the activity models and symbols which represent values usable by the activity models and metadata configured to identify the workflow execution model. The computer system also receives user input requesting workflow elements and accesses the database to provide the requested workflow elements using the generalized workflow execution model.
