<p>Systems and methods are provided that allow for publication delegation through the use of publication authorization rules, where a presentity can allow another entity, e.g., a publisher, to publish presence information associated with the presentity on behalf of the presentity. Additionally, the ability is provided for, e.g., a service provider, to restrict presence information that a presentity is allowed to publish. Hence, publication delegation can be effectuated in cases when a rule matches users (with identities) other than the presentity whose presence information is to be published. Moreover, service provider restriction on the allowed presence information can also be provided in those cases when a rule matches the identity of the presentity.</p> |
