Open Screenplay Format (.osf)
OSF is the open, application-independent screenplay XML — designed so scripts never depend on one vendor, and exactly the kind of open standard we anchor to.

Where it came from
The Open Screenplay Format was published in the early 2010s by Kent Tessman (Fade In’s author) as an open XML schema so tools could interoperate without licensing. Fade In saves it natively inside .fadein archives, and Scrite exports it.
