Re: [ws-calendar] PIM progress and questions - 30 November 2012

I think we get too tied up with the specifics of the XML for xCal.

xCal is designed to be as robust as possible in the face of changes to the spec. For example, it would not be surprising to have the value for a tzid be a url or a uri.

Any system which wants to implement a stripped down version of xcal - or any other representation - is free to do so. But I think to claim conformance they have to be able to handle issues of that kind. If internally to their system that always "know" that tzid is text they can handle it that way - but they'd better fail gracefully if one day they read some xcal with a URL for a tzid.

The last form looks like a multi-valued property.

For each of these specializations you have to build into the application knowledge of the structure of the property (at the time you built your application).

That's fair enough if you're prepared to handle the changes that can occur to the data coming from other systems - but that might mean code changes.

I'd guess the answer is a qualified "yes"

I have been chewing on the many dates we have in WS-Calendar. These are of the format (in XML)

 

            <xcal:dtstart>

                        <xcal:parameters>

                                    <xcal:tzid>

                                                <xcal:text>America/New_York</xcal:text>

                                    </xcal:tzid>

                        </xcal:parameters>

                        <xcal:date-time>2011-05-28T08:45:00</xcal:date-time>

            </xcal:dtstart>

 

Can a specification that claims conformance, and does  not need to communicate with calendar servers,  look like:

 

            <xcal:dtstart>

                        <xcal:tzid>

                                    <xcal:text>America/New_York</xcal:text>

                        </xcal:tzid>

                        <xcal:date-time>2011-05-28T08:45:00</xcal:date-time>

            </xcal:dtstart>

 

Or even like

 

            <xcal:dtstart>

                        <xcal:tzid>America/New_York</xcal:tzid>

                        <xcal:date-time>2011-05-28T08:45:00</xcal:date-time>

            </xcal:dtstart>

Subject: [ws-calendar] PIM progress and questions - 30 November 2012

 

All --

For today's meeting.

I've been filling in the text for the sections (WD01 shows the model only).

On the PIM I have a number of questions to discuss at the meeting and/or on the email list. I'd appreciate your thoughts and comments on these points.

1. The target is the PIM, not MDA; see item 5 for an example mapping to WS-Calendar 1.0.
2. I've seen and heard no comments; since the document is not complete that's not surprising. I hope.
3. For conformance should the relevant parts of WS-Calendar 1.0 be copied with changes? Or referenced with changes?
4. Should the conformance target be the RFCs or WS-Calendar 1.0? I think the latter.
5. I believe that there should be a non-normative appendix (or perhaps a Committee Note) showing the map from the PIM to WS-Calendar 1.0.
6. Should there be other examples of PIM use and the broader MDA perspective? Non-normative, I think.

Thanks!
