The foaf:homepage property relates something to a homepage about it.
Many kinds of things have homepages. FOAF allows a thing to have multiple homepages, but
constrains foaf:homepage so that there can be only one thing that has any
particular homepage.
A 'homepage' in this sense is a public Web document, typically but not necessarily
available in HTML format. The page has as a foaf:topic the thing whose
homepage it is. The homepage is usually controlled, edited or published by the thing whose
homepage it is; as such one might look to a homepage for information on its owner from its
owner. This works for people, companies, organisations etc.
The foaf:homepage property is a sub-property of the more general
foaf:page property for relating a thing to a page about that thing. See also
foaf:topic, the inverse of the foaf:page property.
