Workflow As Library

A 'Workflow As Library' is a Workflow that is registered into MMS and can be used as an Elementary Task in another Workflow.

Let's do an example: assume we have a Workflow retrieving the best Picture from a video. This workflow is composed by several Tasks, a Task looking for Faces into the Video, if it does not find any face (OnError event), there is another Task getting a Picture at a specified instance (i.e.: 30 seconds since the starting of the Video). Then we have the encoding of the Picture and so on. Let's call this Workflow 'Best Picture Of a Video'.

Now, let's assume we have another Workflow registering a live feed and generating a chunk (video media item) every 60 seconds. We want to have a picture for every chunk generated during the registration.

To achieve this, we will register the 'Best Picture Of a Video' Workflow into the MMS as 'Workflow As Library'. Then we use it into the new Workflow as we usually do with any Elementary Task.
