3. 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

4. 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

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

6. 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

7. 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

8. 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

9. 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

10. 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

11. 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.
