First, since the general position has been that, as a nonvoting member, my comments do not count toward the quorum, I make these observations on IPP Everywhere vs. Cloud “Use Cases” as comments on the conference call rather than last call comments on the document. Second, I am noting the divergence of the two use cases from the same original set not as critical comments on the IPP Everywhere Use Cases, but to indicate the legitimate differences in how one looks at these cases. I can think of no reason why the two sets of use cases must be the same in style, form or specifics, provided that they are realistic and useful in developing requirements. Further, I believe it is valid to conclude that a requirement evolving from a Use Case need not be addressed in thesolutions, provided that a reason for the omission is given. However, in that there were some issues that came up in addressing the IPP Everywhere use cases that had also been addressed in the Cloud Use Cases, I offer this summary.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>With that preface, I would note that the original Use Cases included both concise statements of cases where a specific feature would be used (which I would call Use Cases), and narratives giving a more or less plausible situation (perhaps better called scenarios). The IPP Everywhere spec gives specific use cases under “Select Printer” , but reverts to more of a scenario approach for the “Print” section. I see no problem with this approach although I admit a bias toward stating scenarios, with the requirements developed from the scenarios breaking out the details (e.g., specific criteria used for selection). <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>One line of thinking in the Cloud discussion was that requirements were to be developed to address use cases (or scenarios) and the design was to be developed to satisfy the requirements. Therefore, it seemed inappropriate to describe the Use Cases in terms of the elements of the model design. So the Cloud scenarios were rephrased in terms of the basic elements…the User (or more specifically, the potential Job Originator), the physical printer and the stuff in between (primarily the Cloud , the big black box in the sky). I do not suggest this as a comment on the IPP Everywhere specification, just as the thoughts that are reflected in the Cloud Rationale section. <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>With regard to specific changes in the Cloud vs IPP Everywhere versions of what was initially the same use case:<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoListParagraph style='text-indent:-.25in;mso-list:l0 level1 lfo1'><![if !supportLists]><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><span style='mso-list:Ignore'>1.<span style='font:7.0pt "Times New Roman"'> </span></span></span><![endif]><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>If Common Preconditions in Cloud were important, it was felt that they should be itemized and presented as a distinct section.

Even in IPP Everywhere, it is sort of contradictory to say “</span>the Printer must be Visible to the Client in order to be selected, either directly or through an intermediate Service” when “Visible” is defined as the ability to communicate directly. The other confusion developed from the definition’s referring to the “ability” to communicate, suggesting that at some time under some conditions the connection could exist while the normal sense of the word suggests that the connection does exist.<span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p></o:p></span></p><p class=MsoListParagraph style='text-indent:-.25in;mso-list:l0 level1 lfo1'><![if !supportLists]><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><span style='mso-list:Ignore'>3.<span style='font:7.0pt "Times New Roman"'> </span></span></span><![endif]> Print a Document – no significant difference.
