I am trying to find a solution for differentiating business and residential addresses in our schema. I don't see much standard schema which does this nicely.
I use postalAddress and homePostalAddress. The few LDAP directory clients out there that do address entries (e.g. Evolution, Mozilla) understand the distinction, and of course the web clients that I write (using PHP) do too.
BTW: The Mozilla folks have designed their own schema too...
Ciao, Michael.
