FOAF OWL DL

Morning all,
I wonder to use foaf elements in my OWL DL ontology.  Do someone 
experienced  some  OLW DL foaf version? Do exists a recommended one? I 
found just   http://attempto.ifi.uzh.ch/site/docs/OWL_to_ACE/foaf.owl. 
What do you think about it?

Thank you in advance,
Cristiano Longo
