Pray for bandwidth Charter discussion Planned discussions Prioritization of management objects for V1 Look at POPAI limited spec Add new entries to aspect ratio table Next steps: what do we write/rewrite on what schedule Next meeting New business 2

Join the Printer Working Group! If we don't join, we aren't protected by the Intellectual Property policies of PWG and IEEE. If we don't join, we cannot vote to charter this group as a real working group. And PWG will not be able to review or publish our specifications! PWG is very inexpensive, very low-maintenance $1,500 per year per company 3

Intellectual Property Statements PWG/IEEE Intellectual property policies PWG slides All vendors should submit PWG "Letter of Assurance" stating intellectual property claims and non-claims. Additional intellectual property considerations that this group has adopted The management of the state or operating parameters of an object does not impinge on any intellectual property of the operation of an object. This specification includes no information on the subject of patents, trademarks, or licenses. The presence of a management object does not imply a license to implement a related feature using any particular technology. 4

Schedules Tuesday 3/20 Wednesday 9:00 AM - 5:00 PM Dinner? 9:00 AM - 3:00 PM (to let people catch planes) 5

General Discussions - Organizing Data for SNMP General discussion of the structure of management data (All) How we organize the management data into functional groups, tables or repeating groups, and properties Discuss the need for meaningful Descriptions of properties (All) A description that repeats the name does not add useful content. Discussion on naming conventions (Rick) Generating SNMP from the XML poses some challenges. Should Group be named XxxxGroup? Should Table be named XxxxTable? Should properties in tables be named XxxxDescription, XxxxStatus, etc.? Use of upper and lower case. 6

General Discussions - Resettable Counters and Replaceable FRUs Discussion on resettable counters in SNMP (Rick) Do not let user write directly into counter property. Add another property that acts like a function to reset the counter. Discussion on FRU replacements in SNMP MIB (Rick) Similarly, add a property that functions to replace the unit. Resets age counters, stores install date/time if available, increments replacement number, etc. 7

General Discussions - New Object Groups Review contributed group and data item definitions (All) Signal source group (Hiroshi and Koichi) Console group (Rick) Localization group (Rick) 8

General Discussions - Generating SNMP from XML Review of SNMP MIB generation status (Rick) XSL translationn of Properties, Tables, Textual Conventions for enumerated property values Look at sample output Items that still need work DefVal clause now required on SNMP objects If string length nonzero, must have a sensible value, e.g., "No description supplied" Use Counter32 and Gauge32 But they cannot have ranges applied Use Integer32 for Gauge Remove ranges from Counters Change concept of multiple tables in a group Causes problems writing Conformance clauses May need to do SNMP V1 MIB also, some tools slow to adapt to V2 9

General Discussions - What's Next after SNMP? What do we want to do after SNMP? (All) Specs for embedded web servers (EWS)? Serial-line interface commands? CIM MOF (Managed Object Format) files for web services? 10

General Discussions - Related Specs POPAI command specs (Nick) Their "spec" is very brief, includes very little of the information that we have tried to capture in our groups and objects. VESA command semantics that may be useful to us (Nick) 11

General Discussions - Trade Shows What show When Where Type of event Who will research Comments NSCA March Orlando trade show Randy Already too late SID May SF white papers, poster papers Nick We may alreay have missed final call for papers InfoComm June 15-21 Anaheim conference and trade show The "Call for Presenters" page is 404, oops CEDIA Sept 5-9 Denver training and trade show tbs NAB April 14-19 Las Vegas Rick Session schedule already fixed 12

General Discussions - Recruiting AMX Controls, Dallas, TX Already contacted by Nick Extron, Anaheim, CA (near LA) Crestron, Rockleigh, NJ (near NY) InFocus Already contacted by Rick Trans-Lux Just discovered 13

Next Steps - 1 Re-draft the XML Finish the groups we haven’t done yet One table per group Naming conventions: hierarchical, remove unnecessary prefixes Make Optionality match the spreadsheet Review ranges on gauges; remove from counters Reset property Better descriptions Look at default values carefully Be sure we add missing items Finish the groups we haven’t done yet Alerts Localization Interfaces Audio 14

Next Steps - 2 Publicity Recruit! Everybody join PWG Nick look at CEDIA for opportunities Nick & Rick look at ezines Recruit! RR & Nick get some names Get POPAI involved, give them our semantics as starting point Everyone go to InfoComm. Need a flier.
