Introduction + + This IANA Charset MIB [CHARMIB] module defines the single textual + convention 'IANACharset'. Once adopted, all future versions of the + IANA Charset MIB [CHARMIB] may be machine-generated whenever the IANA + Charset Registry [CHARSET] is updated by IANA staff according to the + procedures defined in [RFC2978], using the utility [CHARGEN] + described in section 3 of this document or any other machine- + generation method. + + It is strongly recommended that future updates to the IANA Charset + MIB [CHARMIB] be machine-generated (rather than hand-edited) to avoid + asynchrony between the IANA Charset Registry [CHARSET] and the IANA + Charset MIB [CHARMIB]. + + Note: Questions and comments on this IANA Charset MIB [CHARMIB] + should be sent to the editor (imcdonald@sharplabs.com) and IANA + (iana@iana.org) with a copy to the IETF Charsets mailing list (ietf- + charset@iana.org). + +1.1. Conformance Terminology + + The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", + "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this + document are to be interpreted as described in BCP 14, RFC 2119 + [RFC2119]. + +1.2. Charset Terminology + + The following terms are used in this specification, exactly as + defined in section 1 'Definitions and Notation' of the IANA Charset + Registration Procedures [RFC2978]: "character", "charset", "coded + character set (CCS)", and "character encoding scheme (CES)". + +2. The Internet-Standard Management Framework + + For a detailed overview of the documents that describe the current + Internet-Standard Management Framework, please refer to section 7 of + RFC 3410 [RFC3410]. + + Managed objects are accessed via a virtual information store, termed + the Management Information Base or MIB. MIB objects are generally + accessed through the Simple Network Management Protocol (SNMP). + Objects in the MIB are defined using the mechanisms defined in the + Structure of Management Information (SMI). This memo specifies a MIB + module that is compliant to the SMIv2, which is described in STD 58, + RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579], and STD 58, RFC 2580 + [RFC2580]. + + + +McDonald Informational [Page 2] + +RFC 3808 IANA Charset MIB June 2004 + + +3. Generation of IANA Charset MIB + + Intellectual Property: The C language utility 'ianachar.c' [CHARGEN] + and the IANA Charset MIB template file [CHARTEMP] are hereby donated + by the author (Ira McDonald) to IANA, in perpetuity, free of license + or any other restraint. + + The [CHARGEN] utility may be used to generate an updated version of + the 'IANACharset' textual convention by reading and parsing the + (currently plaintext) IANA Charset Registry [CHARSET]. + + This utility parses each charset registration, finding (in order): + + 1) The 'Name' field (which is saved for a fallback - see below); + + 2) The 'MIBenum' field (which contains the IANA-assigned positive + decimal enum value); and + + 3) The (usually present) 'Alias' field that begins with 'cs' (that + contains the IANA-assigned enum label). If an 'Alias' field is + not found, the utility constructs one from the 'Name' field by: + + - Beginning the enum label with a lowercase 'cs' prefix; + + - Copying _only_ alpha/numeric characters from the 'Name' field + to the enum label (ignoring punctuation, whitespace, etc.). + +4.

IANA Considerations + + IANA has assigned a base arc in the 'mgmt' (standards track) OID tree + for the 'ianaCharset' MODULE-IDENTITY defined in the IANA Charset MIB + [CHARMIB]. + + Whenever any 'charset' is added to the IANA Charset Registry + [CHARSET], a new version of the IANA Charset MIB [CHARMIB] may be + machine-generated using the C language utility [CHARGEN], described + in section 3 of this document or some other utility. + +6. Internationalization Considerations + + The IANA Charset MIB [CHARMIB] defines the 'IANACharset' textual + convention that may be used in a given MIB module to supply explicit + character set labels for one or more text string objects defined in + that MIB module. + + For example, the Printer MIB [RFC1759] defines the three character + set label objects 'prtLocalizationCharacterSet' (for description and + console strings), 'prtInterpreterDefaultCharSetIn' (for received + + + + +McDonald Informational [Page 10] + +RFC 3808 IANA Charset MIB June 2004 + + + print job input data), and 'prtIntpreterDefaultCharSetOut' (for + processed print job output data). + + The IANA Charset MIB [CHARMIB] supports implementation of the best + practices specified in "IETF Policy on Character Sets and Languages" + [RFC2277]. + + Note: The use of the 'SnmpAdminString' textual convention defined in + [RFC3411], which has a fixed character set of UTF-8 [RFC3629], is + STRONGLY RECOMMENDED in defining new MIB modules. The IANA Charset + MIB [CHARMIB] supports locale-specific MIB objects with variable + character sets. + +7. Security Considerations + + This MIB module does not define any management objects. Instead, it + defines a (set of) textual convention(s) which may be used by other + MIB modules to define management objects. + + Meaningful security considerations can only be written in the MIB + modules that define management objects. Therefore, this document has + no impact on the security of the Internet. + +8. Acknowledgements + + The editor would like to thank: Bert Wijnen (Lucent) for his + original suggestion that the 'IANACharset' textual convention should + be extracted from Printer MIB v2 [RFC3805]; Ron Bergman (Hitachi + Printing Solutions) and Harry Lewis (IBM) for their many years of + effort as editors of Printer MIB v2 [RFC3805]. + +9.
