It is still inverse functional.

If multiple contacts want to share an email address then all of them can
link to the same nco:EmailAddress. I do not think we need a separate copy
of the nco:EmailAddress for each contact.

Something like this -

<nepomuk:/resA> a nco:Contact ;
                           nco:hasEmailAddress <nepomuk:/res/email> .

<nepomuk:/resB> a nco:Contact ;
                           nco:hasEmailAddress <nepomuk:/res/email> .

<nepomuk:/resC> a nco:Contact ;
                           nco:hasEmailAddress <nepomuk:/res/email> .


<nepomuk:/res/email> a nco:EmailAddress ;
                           nco:emailAddress "email at email.com" .

If the Nepomuk identification works perfectly then this is what we
currently have.
