As per my understanding of presence data model, Presence state = person information + his services + his devices. Furthermore, person information like activities have to me one and the "person" can have multiple services or devices thus multiple tuple in a single PIDF.
Does it really makes sense to have multiple "person" as output of Presence Engine (Compositor)? If XMPP supports multiple "person", does presence data model has a deficiency modeling this behavior? ~Vikram On 6/15/07, Vikram Chhibber <[EMAIL PROTECTED]> wrote: > The way this is achieved in SIP is to simulate multiple PUBLISH being > sent by different devices for the same user to the Presence Engine. > This is perfectly valid. > The Presence Engine needs to be smart enough to do a composition and > output the most reliable "person" information to the watchers.
