Photoshop :: Where Are Directions For Using A Metadata Template

Photoshop displays metadata for images, including Camera Data.  The latter can include Owner, but it is not told where that information comes from.  It is possible that it comes from a “metadata template” as accessed by the second of the four tabs at the bottom of the Camera Data screen.  There is a folder: User>Library>Application Support>Adobe>IMP>Metadata Template, but that latter folder is empty, and (quite naturally) there exists no directions for setting up any metadata template.  At least one does not turn up from searching the Adobe website.There are vague hints about the existence of direction (as at URL...), but no specific directions where they are actually likely to be needed.
