A user task is a unit of work that must be carried out by a user. A user task comprises of one or more Ooyala Flex console screens (or a wizard), through which a user interacts with Ooyala Flex to get work done. A user task is a workflow-based concept and user tasks are always carried out as part of a workflow.
Examples of user tasks are:
New task instances are created when a workflow instance moves to a user task node.
To really understand user task orchestration in Ooyala Flex, it’s important to understand the difference between a task definition and a task instance.
A task definition defines the type of task and the work to be carried out by a user. Task definitions are used to create user task nodes in workflow definitions.
There are some fundamental rules that apply to all valid task definitions:
A task instance represents a single instance of a task definition. A task instance is created when a workflow instance reaches a user task node. Once the task instance has been created and assigned, it can be accessed from the My Tasks section of the Ooyala Flex console. Once the task Instance has been completed, the workflow instance that created the new task instance is notified and the workflow instances moves to the next node.
Think of a task definition as a list of instructions for doing a specific task and information about who should follow these instructions. Although this task definition defines the instructions for carrying out a specific task, it isn’t a task itself. A single task definition with a list of instructions can be used to carry out lots of instances of work against lots of individual assets. Each individual unit of work as an “instance” and the list of instructions to follow as the “definition”. In summary, a task definition defines what must be done and who must do it. A task instance is a single instance of these instructions which must be carried out by a single user.
A user task is a workflow concept that links together a user and a wizard that comprises of pages. Hence a task type is synonymous with a wizard. Both refer to an ordered sequence of pages, through which you interact with Ooyala Flex in order to carry out work. Ooyala Flex’s task definition and wizard framework is very extensible so that developers can create their own task types and wizards with their own associated pages.
Below we have listed some of the task types that Ooyala Flex provides “out of the box”.
It’s important to understand the difference between a user task and a wizard. A user task references a wizard and must be carried out as part of a workflow. A wizard is a user interface component that offers a sequence of pages or screens that must be worked on in a specific order. A wizard does not have to be carried out as part of a workflow and can be run in “stand-alone” mode.
