When you open a presentation for editing, it is saved as a project. Each change you make to a project, Mediasite automatically saves and lists it in the project's revision history. Once you are finished editing, you can save your changes to the original presentation, to a new presentation, or to an existing presentation.
Each time you commit a change to a presentation, a job is created for it. A presentation can have multiple projects, each with its own commit jobs. For each job, its status and time it was executed or completed are listed along with a bar showing its progress. A job can have three possible states: completed, working, and failed.
