Michael,
Although this is a great outline, it may give the impression that the PWG
were intending to develop a Cloud Printing specification; from recent
comments, it is not clear that we are or can. Indeed, there are already
various Cloud Printing implementations deployed. I think that we are agreed
that the PWG would like the basic printing semantics to be consistent with
the PWG model, regardless of the implementation; this would not only provide
a more consistent print capability for users, it would facilitate making the
actual printers compatible with the various implementations. Hopefully, we
could also encourage greater interoperability and thereby make more devices
available to users (thereby increasing printer use).
We have already stated what we consider to be the basic characteristics of
Cloud Printing. I think the next steps are to better understand the various
implementations and consider, from the printer perspective, to what extent
the semantics are or can be made consistent with the PWG model, and perhaps
what must be added to the model. I would therefore cast this outline as a
review of these aspects in extant or imminent Cloud Printing implementations
rather than giving the impression that we intend to specify these things.
Certainly, after we understand what has/is being done, we can consider from
a printing viewpoint, to what extent they are compatible with the PWG model,
what other solutions we might consider more compatible for interoperability,
and indeed where our model may need to be improved.
Thanks,
Bill Wagner

Subject: [Cloud] Draft agenda/slide outline for February Cloud Printing BOF
All,
In the interests of making the next Cloud Printing BOF as productive and
useful as possible, here is a draft agenda/slide outline for the February
face-to-face. Please provide feedback no later than January 27, 2011 so we
have time to finalize the slides.
Thank you!
Agenda/slide outline:
1. Summary of functional model
* Client
* Cloud Print Provider
* Cloud Print Manager
* Printer
2. Requirements
* Registration/discovery/selection
* Job tickets
* Document data/formats
* Fidelity/late transforms
* Event notification
* Encryption for privacy/security
* Logging/accounting
* Firewall/router/network traversal
3. Attributes
* Geolocation information
* Job, printer, and subscription UUIDs
* Various types of credentials
4. Document formats
* CUPS Raster
* HTML/XHTML
* JPEG
* PDF
5. Protocols
* HTTP
* IPP
* JSON
* REST
* SMTP
* SOAP
* WSDL
* XMPP
6. Next steps
* Do we have more to talk about?
* If so, more BOFs or is there sufficient interest and participation
for a dedicated Cloud Printing WG?
* Are we going to write any standards or recommendations?
* If so, what working group(s)?
