The Identify Services operation informs something in the Cloud (I think it is an existing specific Cloud Imaging System, but I suppose it may be a generic something) of the Services that are to be registered. The Cloud entity responds with its supported Cloud Imaging Services, either created in response to the Proxy operation or preexisting. However, since we agree that the Cloud Service may be pre-existing, we cannot construct the registration model on it being created in response to the registration; nor can we assume that the elements of the Cloud Service will necessarily correspond with the elements of a specific Device Service.<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'>We have maintained that, in normal operation, the Proxy communicates Print Service information to the Cloud Print Service, Scan Service information to the Cloud Scan Service, etc. It seems reasonable that in registering a specific service, the Proxy communicates with the corresponding Cloud Service. Therefore, I suggest that the Proxy send Device Service Elements to the corresponding Cloud Service to register a Device Service. However, we have some options introduced that may not have been obvious when considering just a Cloud Print Model.<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'>We are dealing with Imaging Systems, both in the Cloud and in the Device, not just services.<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'>2.<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'>There can be multiple Imaging Services, including multiple Imaging Services of the same type, in an Imaging System<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]><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>There may be elements of a Device Imaging Service as well as Services in a Device Imaging System that the owner may not wish to make accessible to the Cloud.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>In a trivial case where there is just one Service or all elements of all services are to be registered with all corresponding Cloud Imaging Services in a Cloud Imaging System, Owner interaction may be just identifying the Cloud Imaging system.
