Systems and methods for cloud-based file sharing, where templates are provided for creating workflow instances which enable the sharing of managed objects. Reusable workflow templates are stored in the repository of a cloud-based file sharing system as objects that define components of the workflow, or placeholders for these components. A user instantiates a workflow instance from one of the templates and configures the workflow instance to identify content objects or forms, tasks related to the content objects, and users assigned to perform the tasks. The workflow instance is stored as an object in the repository. Users assigned to tasks are authorized through the workflow instance to access the content objects or forms to perform the tasks.
