Easy changes first: good idea.  One, maybe two, CRs; maybe enums are separate, since they're sizable and substantive.  Don't bother with white papers.  Draft directly into CR format, then edit as needed.  Don't bother with PWG private extensions.  Propose phase 3 changes as experimental.  Then the implementation experience of two companies will be needed to promote the changes to full status.  Do UML diagrams first for the new class structure, and get agreement on the structure before writing a lot of text.  Core needs some overview of the printing model.  (Printer MIB has a good intro.  Where is the  similar overview for IPP?) Use Capabilities and Settings classes (CIM_xxxx) to express such for printers.  The usual division is - What is the device capable of? (r/o in Capabilities) - What has the manager requested of the device? (r/w in Settings) - What is the device actually doing? (properties in the device class itself) (These classes are not completely straightforward, as I recall.  I will look for some examples.) Think about doing a profile in the long term.  (A really good idea.  I will explain this and get an example for PWG to look at.  I think we should draft the profile along with the UML.) For the major changes, be sure to include some consideration of - related element causing error - health and status - messages - indications (event notifications in CIM, related to traps, alerts, alarms, etc.) Send draft things, if we wish, to John Crandall and Jon_Hass@dell.com, or to wg_cimcore@dmtf.org Gotta go.  rick ------------------------- Richard_Landau(at)dell(dot)com, System Mgt Arch & Stds +1-512-728-9023, One Dell Way, RR5-3 Box 8509, Round Rock, TX 78682 </BODY> </HTML>
