this kind of privacy is affecting the calls as well, for example. I can
send you a call or other SIP request to discover you are online/offline.
So this is another service that should be applied globally: black-white
lists.
Having a mechanism just for presence is another bad design.
i agree and i implemented xcap_auth_status() function just in order to
be able apply xcap rules also to MESSAGEs and INVITEs. there should be
different events for those though.
There is no invite-rules neither message-rules specifications for
XCAP, neither for XDM (OMA additions), just pres-rules. So we would
end implementing a supposed "standard" but always introducing custom
specifications to make it "logical". Then clients should also
implement these custom extra layers of specs in order to interoperate
properly.
When it's required to add custom specifications it means that:
- The core "standard" specifictions are not good or not enough.
- Interoperability will be a pain.
For me SIMPLE/XCAP is dead many months ago.
if ever it was really born :-)
Still there are some good concepts that can be re-used.
I see xcap as a service offered by the telephony provider, maybe in the
way CPL was designed and somehow forgotten -- iirc, with CPL you can
block users.
