Well, no. I'm saying that the Agent named "Jonas Smedegaard" *has* an
account. foaf:account is the replacing foaf:holdsAccount, it seems (see
http://xmlns.com/foaf/spec/#term_holdsAccount).

Hence, the unicity, on webid.debian.net of the foaf:accountName of the
OnlineAccounts (since it is the email) whereas the foaf:name of the
Agent allows homonymy.

So I hope these RDF representations will semantically correct now.

Tell me if I've overlooked details and made a mistake.

Best regards,

P.S.: there's apparently a bug in that
<http://webid.debian.net/maintainers/dr%40jones.dk#agent>'s
foaf:firstName is 'Maintainer:' :-/ ... will see if I can spot the
culprit perl code ;)
