Hi
Simith was correct about the draft. draft-ietf-simple-presence-rules-04 (Presence Authorization Rules) defines a format for presence authorization Policy. Also, draft-ietf-geopriv-common-policy-06 gives a framework for representing authorization policies. This draft is the basis for presence authorization Policy as well.

However, this is not the scenario I am talking about. In this case, A publishes its event package to Presence server P. If B wants to subscribes to A's event package, it subscribes to P (which acts on behalf of A). Now, the only way A knows if B is subscribing to its event package is to subscribe using watcher info. The RFC provides a way in which P can NOTIFY A that B is subscribing to the package. However, it does not discuss a mechanism where A can "instruct" P to deny the subscription (in other words, P does not have enough authentication information to allow this particular user B). regds arjun On 1/17/06, SiM <[EMAIL PROTECTED]> wrote: > > > > *Arjun Roychowdhury <[EMAIL PROTECTED]>* wrote: > > Hi, > RFC 3857 "A Watcher Information Event Template-Package...." defines a > mechanism by which a user can subscribe to subscription changes to a > particular event package. > > I am working on a situation where user 'A' is the 'moderator' of a > particular event package X that is hosted in a central presence server P. > A > subscribes to P with > event:X.winfo. > > Now when B subscribes to P for event X, P notifies A of this occurence. > However, 3857 provides no standard mechanism in which A can > instruct/deny this request (3857 leaves this as 'out of scope'). > > Is there any draft / mechanism that allows an explicity 'allow / deny' > mechanim via SIP that A can use to instruct P to deny the subscription > to B ? > > regds > arjun > > Hi Arjun, > I'am not sure whether you are looking for the below > Internet draft on Presence Authorization Rules, where a user can, > express his/her intent (Rule) to share presence information, to a > particular Subscriber .
