Hi Rick,
Agreed - I was tired when I read your note and confused about the context.
Cheers,
- Ira

Huh? I'm puzzled.
- The "Section 4" example in your email was entirely correct, and they will
agree as soon as we send them a couple words of context.
- MIB references in MappingStrings are explicitly different. The examples
in the CIM Infrastructure Spec and dozens of MOFs use exactly the syntax you
want, also, that is
MIB.IETF|Printer-MIB.prtCurrentLocalization
- MIFs also have a special format. Fortunately we don't have to deal with
any of those. (Harry rescued printers from MIFness many years ago, thank
you Harry.)
After reading the actual so-called rules on this topic, in the CIM
Infrastructure Spec (DSP0004), sections 2.5.5 and 2.5.6, I was very
confused. However, after looking at many dozens of citations in the
existing MOFs, I find that there is much consistency. And the formats you
proposed match nicely.
Let's declare victory and move on.

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.
