[Simple] RE: Comments on PIDF-Manipulation Usage-00draft (was RE: Comments on draft-isomaki-simple-xcap-publish-usage-00)

Hi George,

I think you may still missing the point that there is not only one but several presence documents that can be published by a presentity, and only at the event state compositor do they get combined into a single document. For instance each PUA publishing with SIP PUBLISH will have its own separate PIDF-doc. The draft does not propose those documents to be manipulated by XCAP, so there is clear separation between "soft state PUA-specific" presence and "hard-state device-independent" presence. What the draft proposes is that there woud be a single device independent "hard-state" presence document in addition to the PUA-specific ones. The motivation is given in Chapter 1 and the model is illustrated in Figure 1. 

So in short: The "hard-state" and "soft-state" tuples are kept in separate documents, and the scenario you describe below won't exist.

What exactly would go into the hard-state presence document is not defined in the draft, and  is left for an implementor or user to decide. Typically there could be things like web-page address, e-mail specific tuple, or even some tuples with the future-status, i.e. something that is not tied to a single device and/or does not change very often. Also this document would form the basis for the outgoing presence information in the absense of any publishing PUAs.

Hi Markus,

Lets leave the mandatory-ns element aside for the time being.
You stated that one should use XCAP to control *hard state* tuples only
What if a user changes other  soft tuples with XCAP.

Will the server allow that?

Where in your draft you explain/discuss how to handle those cases?

And what are the tuples in PIDF and other extensions that you consider *hard state* tuples.
