The foaf:follows property relates a foaf:Agent to another
foaf:Agent whose activities they (in some sense) follow.
The foaf:follows relationship does not imply complete information flow
between parties, and should not be taken as evidence that any agent will
necessarily be aware of some particular activity. Typical use is to indicate
subscription or follows within Web based services such as social networks, microblogs
life-streaming and news syndication services.
This property is neither function, inverse-functional, nor symmetric.
