Nicknames A nickname is represented as a combination of a Display-Name and a URN. URNs present two interesting properties. URNs are not routable, just names -> allows some anonymity. URNs are hierarchical => allows to scope the namespace to that of the conference, MSRP switch, etc. Nicknames can be learnt from the conference event package. Nicknames can appear in the From, To, and Cc header of Message/CPIM and the Distribution header in MSRP. Example of Nickname in Message/CPIM: From: "Prince of the snow" Open issue: how to negotiate nicknames to guarantee uniqueness at least within a conference? |
