Hi Bijan,

Quick question, would these 'legitimise', and enable OWL tools to work with
foaf:mbox_sha1sum (allowing person-identity smushing as with
foaf:mbox, which is an ObjectProperty IFP)?

foaf:mbox_sha1sum
    a    r:Property, owl:DatatypeProperty, owl:InverseFunctionalProperty;
    s:comment
        "The sha1sum of the URI of an Internet mailbox associated with
exactly one owner, the  first owner of the mailbox.";
    s:domain
       foaf:Agent;
    s:isDefinedBy
       foaf:;
    s:label
       "sha1sum of a personal mailbox URI name";
    s:range
       s:Literal;
    vs:term_status
       "testing".

Cheers,
Danny.
