Change History:<br><div><div class="gmail_signature"><div dir="ltr"><div><div dir="ltr"><br>15 September 2016<br><br>- Interim draft – changes per PWG F2F review on 23 August 2016<br>- global – accepted all changes before section 8 (all reviewed at PWG F2F)<br>- global – renamed section 5 to IPP Objects and Operations Summary and revised to delete reference to “system-configured-subunits” and change Description attributes sections from “READ-WRITE” to “potentially READ-WRITE” (consistent with section 7)<br>- global – revised section 6 IPP Operations to replace “allows allows” with “allows”<br>- global – changed “resource-state” keywords of ‘pending’ to ‘created’ and ‘active’ to ‘available,’ added “resource-state” keyword of ‘aborted’, and added “resource-state-reasons” keywords of ‘cancel-requested’, ‘install-requested’, and ‘resource-incoming’ for operations with delayed state transitions<br>- revised section 4 IPP Object Model to add notes that System, Printer, and Resource Owners are mutable (long-lived objects) while Job and Subscription Owners are immutable (short-lived objects)<br>- revised section 4.6 Resource Object to correctly explicitly refer to Send-Resource-Data and Install-Resource operations<br>- revised section 5.3 System Status Attributes and Table 2 to delete reference to “system-configured-subunits”<br>- revised section 5.4 System Operations to include Install-Resource in note 3 and state that the original StoreResource operation has been decomposed into the sequence of Create-Resource, Send-Resource-Data, and Install-Resource and to revise and reference note 4 about Install-Resource<br>- revised section 5.7 Resource Status Attributes and Table 5 to delete “resource-authenticator” and “resource-category” and note 7 about “resource-authenticator”, delete “resource-job-id” and note 5 about “resource-job-id”, and change “resource-printer-id” (singular) to “resource-printer-ids” (a list of explicitly associated Printers)<br>- revised section 5.9 Printer Status Attributes to delete double period on second list item<br>- revised section 5.9 Printer Status Attributes and Table 7 to add “printer-resource-ids” with note about “resource-ids” operation attribute in Create-Printer<br>- revised section 5.10 Job Status Attributes and Table 8 to add “job-resource-ids” with note about “resource-ids” operation attribute in Job Creation operations<br>- revised section 6 IPP Operations to regroup all operations under Printer, Resource, Subscription, and System Operation subsections (this breaks DOZENS of cross-references throughout the document)<br>- revised note in section 6.1.1 Create-Printer and section 6.2.2 Create-Resource to explain two alternatives for correctly populating “printer-resource-ids” and “resource-printer-ids” status attributes<br>- revised section 6.1.1 Create-Printer to add <all mandatory Printer Description attributes> with reference to “system-mandatory-printer-attributes”<br>- revised section 6.1.1.1 Create-Printer Request to add “resource-ids” operation attribute that requests Resources and is copied (if valid) to the “printer-resource-ids” Printer Status attribute – note that this is intentionally NOT a Printer Description attribute for security<br>- revised section 6.1.3 Get-Printers and section 6.1.4 Get-Printer-attributes to state that the returned Printers and Printer attributes MAY be filtered based on Client access rights (i.e., the value of “requesting-user-name”) or the specified “document-format”<br>- revised section 6.1.3 Get-Printers and section 6.1.4 Get-Printer-attributes to list all operation and response attributes explicitly, add optional “printer-uri” alternative to “printer-ids” or “printer-id” for target Printer, optional “document-format” (for filtering returned attributes), and required “printer-xri-supported” in response<br>- revised section 6.1.4 Get-Printer-attributes to discuss backwards compatibility, change “system-uri” target to “Client SHOULD supply” (for legacy IPP Clients), add back optional “printer-uri” (for legacy IPP Clients), add “first-index” and “element, and change “Groups 3 to N” to “Group 3”<br>- revised section 6.2.1 Cancel-Resource, section 6.2.5 Install-Resource, section 6.2.6 Send-Resource-Data, and section 6.2.7 Set-Resource-Attributes to add that if “resource-state” is ‘canceled’ or ‘aborted’ or “resource-state-reasons” includes ‘cancel-requested’ then System MUST return ‘client-error-not-possible’<br>- revised section 6.2.1 Cancel-Resource to correct typos from “Create-Resource” to “Cancel-Resource”, clarify transition of “resource-state” to ‘canceled’ (could be delayed if Resource is in use in a Job) and “resource-state-reasons” to ‘cancel-requested’, change “MAY” to “SHOULD” for the System delete of Resource data, add a definition of the Resource History lifecycle phase, and state that the System MUST support Resource History period of at least 300 seconds for reliable system log files<br>- revised section 6.2.2 Create-Resource to delete “resource-category” (redundant with resource-type), delete “resource-job-id”, and clarify transitions (and keyword names) of “resource-state” and “resource-state-reasons”<br>- revised section 6.4.3 Get-System-Attributes to add note that we will require explicit request for “system-configured-resources” or “system-configured-printers” (by analogy to “media-col-database” for Get-Printer-Attributes)<br>- renamed section 7.1 System, Printer, Resource, and Job Operation Attributes to simply “Operation Attributes” and added note about their applicability<br>- revised section 7.1 Operation Attributes to add “resource-ids” for Create-Printer and Job Creation operations to list requested Resources<br>- deleted section 7.1.7 resource-category operation attribute<br>- deleted section 7.1.10 resource-job-id operation attribute<br>- revised section 7.2.11 resource-settable-attributes-supported to add missing type<br>- revised section 7.2.13 system-default-printer-id to keep “MAX” and delete “max” in type<br>- added section 7.2.18 system-mandatory-printer-attributes and Table 9 – Mandatory-to-Supply Printer Creation Attributes for use in Create-Printer operation<br>- revised section 7.3.11 system-configured-resources and Table 10 to delete “resource-category”<br>- deleted section 7.3.11.1 resource-category (redundant with resource-type)<br>- revised section 7.3.17 system-state-reasons to state that any applicable “printer-state-reasons” keyword value can be used (to avoid enumerating the existing keywords here)<br>- revised section 7.5.3 printer-service-type to add ‘print3d’, delete ‘emailin’ and ‘emailout’ (security nightmares), delete ‘vendor’ (not interoperable), and add ‘smiNNN-name’ pattern and explanation for vendor service types<br>- revised section 7.7.x “[date-time|time]-at-[cancelation|creation|installation]” to state the timestamps MUST be set at the time the System accepts a Cancel-Resource, Create-Resource, or Install-Resource operation (instead of when the process completes and the appropriate “resource-state-reasons” pending value is removed)<br>- deleted section 7.7.4 resource-authenticator (access info must be included in resource data manifest file)<br>- deleted section 7.7.5 resource-category (redundant with resource-type)<br>- deleted section 7.7.9 resource-job-id (use “job-resource-ids” in Job for association)<br>- revised section 7.7.10 resource-state to define ‘pending’ (after creation), ‘available’ (after upload of data), ‘installed’ (after installation), ‘canceled’ (by Client, not by System), and ‘aborted’ (by System) so that ‘canceled’ and ‘aborted’ are the two alternative terminal states<br>- revised section 7.7.12 resource-state-reasons to define ‘cancel-requested’, ‘install-requested’, and ‘upload-requested’ for delayed completion of the respective operations processing<br>- revised section 7.7.16 resource-type to change reference to “resource-category” reference (an attribute) to simply “resource category” (a prefix for a resource-type) and insert explicit resource category prefix into all “resource-type” keyword values and add ‘template-printer’ for potential Create-Printer extension<br>- revised section 14.1 Normative References to add “PWG5100.P3D” for ‘print3d’ service type<br>- added Appendix A – Rationale for Design Choices – added first Resource topics<br><span style="background-color:rgb(255,255,0)">- TODO – add status-code text to section 6 preamble and to all operations in sections 6.x<br>- TODO – add back explicit full parms for every operation in section 6 per PWG F2F review<br>- TODO – fix all the broken section 6.x references from the reorganization of section 6 </span><br><br><div style="display:inline"></div><div
