Hi Rick
 
They're all wet - they don't know their own IETF MIB reference syntax!
 
Quoting verbatim from CIMv2.11 'CIM_BGPProtocolEndpoint.mof':
 
  MappingStrings { "MIB.IETF|BGP4-MIB.bgpConnectRetryInterval" }]
 
Note, none of this pseudo-pipe syntax - THOUSANDS of examples
in the above syntax in CIMv2.11.  These guys should read their
own stuff.
 
Cheers,
- Ira

Went well.  Not perfectly, which is my fault but easily fixed.  Discussion
points: 

- MIB.PWG okay.  

- Hyphen instead of dot okay.  The only reasonable alternative is %2E or
some such, which is much more hostile to humans.  

- "Section 4" was questioned.  I, unfortunately, could not get the doc
(PWG5101.1) open in time to look at the section, and I didn't remember it.
The group's statement was If there is a table or data structure containing a
property, one should use pipe syntax, e.g., 

    doc.authority | structurename | propertyname.  
See examples in the new association CIM_SCSIInitiatorTargetLogicalUnitPath,
which is, horrors, a three-way association, but includes several examples of
this syntax, e.g., 

    MP_API.SNIA|MP_PATH_LOGICAL_UNIT_PROPERTIES|deviceFileName 

HOWEVER, that doesn't apply to the PWG5101.1 "Section 4 Media Color Names"
case, anyway.  As I read it, Section 4 is a textual convention, one of three
in the doc, which might be specified as a syntactic restriction on any
number of properties in other specifications.  There is no property name
within a structure to be cited.  I assume that the same reasoning would
apply to any other textual convention if there were no other formal syntax
to apply.  The IANA textual conventions that we cite do have a reasonable
structure because they are defined in MIBs, so that case is not comparable.
Conclusion: no problem.  

I closed off the debate by saying that we would take a look at it and send a
revised email with context so that they could understand the "Section 4"
case, however we resolved it.  We should send a very simple revised message
(again to wg-cimcore), with wording about textual conventions but not in
formal MIB or other syntax, and maybe an extract of Section 4 from the
document, declare victory, and move on.  Ira, can you make the slight
additions?

Also, a nit, I found a minor typo in PWG5101.1 when I was looking at our
friend Section 4: the first para ends with "...as defined in Table ."  It
should say "Table 1."

Have a good weekend, all.
