You should expect any number of any property in FOAF.
The way these things are restricted in RDF is by using OWL (Web
Ontology Language). OWL lets you set ranges on the numbers of a
particular property allowed. The current schema for FOAF doesn't
include any cardinality restrictions or functional properties (max/min
cardinality = 1)
