Hi Bob,

Actually I did NOT mean to discriminate between objects which
happen to be 'read-only' in the Printer MIB versus ones which
are 'read-write' for the 'PrtStaticLocaleDisplayStringTC'
string objects.

Out-of-band protocols and/or local console interactions by
system administrators may ALSO change the value of 'read-only'
objects.

My MAIN point w/ 'PrtStaticLocaleDisplayStringTC' is to
provide unambiguous information about the language, country,
and code set of these strings for use by both vendor-specific
and open systems print clients and monitor applications.
That is what my FujiXerox peers are also most concerned
about.

Cheers,

PS - Why did you bother to give this constructive input
and criticism in the following note and then (in your
subsequent) note demand the removal of ALL of my suggested
changes for localization clarifications? But thank you
for the useful input and discussion anyway...

Ira,

I think this solution is better than the one in the latest draft of the =
Printer MIB, but I'm afraid that it needs to be carried further. There =
are two types of objects of type PrtStaticLocaleDisplayStringTC, =
read-write and read-only. I think it is only the read-write objects you =
want to be of type PrtStaticLocaleDisplayStringTC since the read-only =
objects (e.g., prtInputVendorName, prtInputModel, prtInputVersion, =
prtInputSerialNumber...) cannot be localized if the printer does not =
contain the needed information. Furthermore, should localization =
information for the previously mentioned objects be added in order to =
allow the management application to know how to display those objects?

Reply To: PMP> New Printer MIB draft

Hi Lloyd, Angelo, and PMP folks, Thursday (26 June 1997)

During a break in this afternoon's IPP Telecon, Lloyd Young brought
hardcopy of yesterday's draft of the Printer MIB into the Nashua
conference room. A brief, lively discussion ensued.

Angelo Caruso suggested to me (and others in the conference room) that
an even BETTER way to specify the 'static' locale of a managed system
(than using an index into an entry in the 'prtLocalizationTable') was to
permit a remote management station (eg, system admin client tool) to Set
a locale which may NOT be currently 'known' to the managed system (ie,
the static locale may be 'opaque' to the managed system - not among the
locales 'known' via ROM/disk/etc).

ASN.1 for Angelo's suggestion follows (if someone else in the conference
room actually suggested the idea, my apologies - it was a little tricky
listening in this afternoon).

Cheers,
- Ira McDonald (outside consultant at Xerox)

---------------------- Improved Static Localization --------------------

UPDATE the following (2) textual conventions in the Printer MIB (flagged
with double-arrows '>>' at updated lines):

PrtStaticLocaleDisplayStringTC ::=3D TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"The type for human-readable (NOT binary) string objects:
a) whose static locale (language, country, code set) shall be
>> indicated by the combination of the values of
>> 'prtGeneralStaticLocale[Language|Country|CodeSet]';
b) whose value (when updated by an SNMP Set-Request) shall be
interpreted in this locale by the management agent;
c) whose value (when returned by an SNMP Get-Response) shall be
interpreted in this locale by the management station."
REFERENCE
>> "See: 'prtGeneralStaticLocale[Language|Country|CodeSet]'
>> in the General group of this Printer MIB."
SYNTAX OCTET STRING (SIZE (0..255))

PrtEnglishASCIIDisplayStringTC ::=3D TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"The type for human-readable (NOT binary) string objects:
a) whose static locale (language, country, code set) shall be
composed of the English language (invariant), any country
>> (indicated by the value of 'prtGeneralStaticLocaleCountry'),
and the NVT ASCII code set (invariant);
b) whose value (when updated by an SNMP Set-Request) shall be
interpreted in this locale by the management agent;
c) whose value (when returned by an SNMP Get-Response) shall be
interpreted in this locale by the management station.

Usage: If the locale country is NOT 'English-speaking', then
the code set shall nonetheless be NVT ASCII (a 7-bit code set!)
and keywords/tags shall be in the English language (specified
by an appropriate IETF or ISO standard, IANA registry, etc), but
other data need NOT be in 'English' (eg, French w/out accents)."

REMOVE the following (1) object from the General group:
