Hi Pete,

Here are my comments.

?Introduction? Section
Line 16 ? I would like to clarify the meaning of "protocol" used here 
?Imaging Peripherals Protocol??  Is this a concrete protocol binding from 
MFD semantic model?  If so, how about ?Internet Imaging Protocol?, being a 
better advancement from "Internet Printing Protocol". Or ?Imaging Web 
Services"? 
 ?Evolution of Semantic Model? Section
1.      Could we have a better title? What about ?Proven and Expected 
Benefits of PWG Semantic Model? ?  Or simply "Benefits of PWG Semantic 
Model" with subsections on "Proven" and "expected" benefits? I think it 
better to use ?Benefits? as the theme and weave the evolution of the 
semantic model as the roadmap to achieve these benefits ? essentially 
telling the ?Why? of the Semantic Model.
2.      With ?benefits? as the theme, I think it?s better to have 
subtitled sections clearly list all proven or expected benefits of PWG 
Semantic Model.
3.      Along with benefits, I think it's better to have the disadvantages 
of full-proprietary approach without a standard that could cost the entire 
imaging device/solution industry be illustrated in parallel to make reader 
truly understand the cited benefits.
4.      Line 28-30 ?The ?gateway? is used here and also line 134 to imply 
a specific architecture component used for concrete protocol mapping 
involving syntactic translation from one data model to the other for 
different protocols.  But ?gateway? has many other meanings in general, 
the use of this term can easily lead to confusion for reader from my 
opinion.

?Model Extensibility and Vendor Differentiation? Section
If we have consensus on changing the title of the previous section to ?
Proven and Expected Benefits of PWG Semantic Model?,  then I think it?s 
better to fold this section under the previous section as a subsection.
?Value of Web Services Mapping? Section
In terms of the "Web Services" technology, there maybe other approaches 
such as RPC, REST, other than SOAP & XML. A brief mentioning of this and 
explain your defintion of "Web Services" here equates to "SOAP protocol 
and XML data binding" approach would be helpful to clear confusion.
Line 59-60 :  I feel some transition is needed from the first paragraph to 
the list of WS-* standard associated with web services.  What are you 
trying to say to the Value of Web Services mapping by listing these 
standards?
Lines 78-82: It?s not clear to me that this paragraph add more value to 
the ?value of Web Services Mapping?.
Like previous sections, I think it's better to also mention the 
disadvantages of other mapping approaches in order to convince readers 
this is the best.
?Effective Standards and PWG?
Line 112-117 beginning with "Proprietary": I got lost here. Is this 
sentence trying to explain the disadvantage of a de-facto standard to 
those PWG members who are not the leader/owner of the de-facto standard? 
Please clarify.
?Internet Printing Protocol Becoming Imaging Peripheral Protocol?
Line 138-139: ?For example, moving IPP to an XML encoding reduces the 
scope of ?attribute-fidelity? to be element-wide instead of 
operation-wide, allowing a more expressive Job Ticket.? How is this a true 
benefit? Please give a concrete example.
Line 140-141: Should the ?IPP view of Print Service? be ?Print Service 
view of IPP?? It?s not clear how the IPP view of Print Service can enable 
the expansion of web services based print service protocol to include 
other MFD services.
It?s very confusing the way ?Semantic model? is sometimes used 
interchangeably with a concrete ?protocol?. Maybe here ?IPP view of Print 
Service? should be stated as ?IPP Semantic Model  view of Print Service??
In all previous section, the word ?protocol? seems to mean a concrete 
protocol mapping of the semantic model?.
We are advancing IPP ?protocol? to web services based Print Service, and 
expanding that to MFD services, why bother to name it backward (in terms 
of technology advancement) to Imaging ?peripheral? ?protocol??  Why not 
?imaging web services??

Subject: Comments needed on MFD white paper



All,

I need comments on the white paper on the goals for the MFD modeling
effort
<ftp://ftp.pwg.org/pub/pwg/mfd/white/GoalForTheMFDModelingEffort20100108
.pdf>. The only changes to this version is the addition of line numbers
and an updated date.   Per our teleconference yesterday comments are due
by close of business Monday January 11.  I will turn the document around
quickly.  The goal is PWG wide distribution on Thursday January 14.

Thanks,

Pete
