SiteVision is using metadata in other ways as well, e.g to decide who the editor is of a page, or width and height of an image in the image archive. In principle it is possible to add metadata to any kind of page or object in SiteVision.

Either you go directly to the tab Information (Metadata) under properties on each page/object, or you can set the value in the window opened when publishing the page. The reason why you can do this is that it is possible to set a metadata field to be a mandatory field, i.e. there must be a value set before publishing. In that case it is a great help to be able to change metadata value when publishing.
A metadata field consists of two parts: a definition and an associated value for each page.
On the tab Information (Metadata) you can see the metadata that are set up on the website:
