Hi,
Forgive the delay in response - I was offline packing for two days.
There's a PWG Semantic Model naming convention for elements here
that's important (and agrees with Mike's intended usage).
In the Semantic Model (and in IPP) there are two distinct base datatypes:
Name (restricted character set, leaving out most non-alpha/non-digit) and
Text (unrestricted character set, except that most control characters are
still invalid).
In Printer MIB, Job MIB, SM/1.0, and IPP there are numerous elements
that are called 'XxxName' (e.g., prtInputName in the Printer MIB) that are
_static_ and SHOULD NOT be changed (or lost across reboots) after
device installation (when the Administrator can override the Factory default
name). Such elements are used in SM/1.0 as _keys_ (for object lookup).
In Printer MIB, etcm there are also numerous elements that are called
'XxxDescription' (e.g., prtInputDescription) that are _dynamic_ and SHOULD
be changed when the current configuration of the element is modified
by an Operator or Administrator. Such elements are never used as keys.
An element called (or used) ppmPortNameOrDescription _cannot_ be added
to the Semantic Model (because it breaks existing strong typing in our XML
schema).
The Apple request can only be satisfied by a separate, dynamic text object.
Cheers,
- Ira

Mike,
The ppmPortName object may contain a maximum of 127 characters.
Does this meet your requirement?

Subject: RE: Adding ppmPortDescription to Port Mon MIB
The intent of this object is to give a short, concise user-friendly name of
the port. It will be presented in the User Interface for and device that
advertises more than one port so the user can pick the correct port for
their connected printer. The whole intent was to differentiate between
multiple ports on a device that could host multiple printers. I am
concerned we will start degrading the user experience if we add a whole
bunch of ports for the same printer with slightly different names.

Ira,
I would like to hear from Mike or Ivan on this subject, rather than rely on
memory.
Your comment does not agree with the current description clause for this
object.

Hi Ron,
Doesn't work - MS specifically said that they wanted PortName restricted
to a _name_ that they will display in their tools and do NOT want it to
include descriptive text. Your memory is incorrect.

Ron,
Thanks for the clarification. In the expectation that manufacturers will
initialize ppmPortName with helpful information, I am satisfied there is no
need to add an additional object.

I remembered this morning why we decided, several months back, to remove
this object.
Since the MIB contained both a desciptive name and a description, it was
agreed that
the two objects were redundant. To clarify this situation I recommend that
the object
ppmPortName be changed to ppmPortDescriptiveName or ppmPortDescription,
rather
than go back to the original redundant pair.
ppPortName is a natural language string with up to 127 characters. For Paul
Danbold's
example I could provide a name such as:
"Networked LPR port providing binary PostScript printing for use by
marketing"
This is less than 80 characters and should be more than sufficient to
satisfy Paul's
requirement.
Also, in addition to a possible name change, it must be noted that this
object is
expected to be administratively configured using an out-of-band method.
Paul, please indicate if this is sufficient.
