Hello,

Sorry if this message appears as a new thread, but I just joined the
list for the purpose of this discussion. Indeed, I work with my
colleague on using OpenXCAP with the Mercuro IMS client, and one of
our questions raised the discussion.

Indeed, I understand the points raised by Anca, but OMA is more
precise than IETF regarding the service URI scheme. As we digged in
the OMA specs (which can be hard to find) I wanted to answer Laurent
Etiemble's last message to point to other specifications.

Regarding the service URI Scheme to be used to subscribe to
modifications on a document stored in a RLS XDMS, it is given in a
document called "Presence Application Characteristics file of Presence
v1.1" which gives the service URI template as :
<xui>;pres-list=<id>
(see 
http://www.openmobilealliance.org/Technical/release_program/docs/PresenceSIMPLE/V1_1-20080627-A/OMA-SUP-AC_ap0002_presence-V1_0_2-20080627-A.txt)
This would mean that the pres-list parameter is the only necessary
parameter to use while requesting subscription to the presence event
for a given list.

Regarding the use of a 409 response to modify the URI on which the RLS
XDMS is requested, this behaviour is described in Appendix B of the
document "Resource List Server (RLS) XDM Specification". You can find
it at : 
http://www.openmobilealliance.org/Technical/release_program/docs/PresenceSIMPLE/V1_1-20080627-A/OMA-TS-Presence_SIMPLE_RLS_XDM-V1_1-20080627-A.pdf

Hope this helps,

Antoine Fressancourt
