16、ISO 639-4:2010 ISO 639-4:2010(E) iv ISO 2010 All rights reservedForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical co
17、mmittees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with th
18、e International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft Internati
19、onal Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be
20、the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 639-4 was prepared by Technical Committee ISO/TC 37, Terminology and other language and content resources, Subcommittee SC 2, Terminographical and lexicographical working methods. ISO 6
21、39 consists of the following parts, under the general title Codes for the representation of names of languages: Part 1: Alpha-2 code Part 2: Alpha-3 code Part 3: Alpha-3 code for comprehensive coverage of languages Part 4: General principles of coding of the representation of names of languages and
22、related entities, and application guidelines Part 5: Alpha-3 code for language families and groups Part 6: Alpha-4 code for comprehensive coverage of language variants BS ISO 639-4:2010 ISO 639-4:2010(E) ISO 2010 All rights reserved vIntroduction ISO 639 provides codes for the identification and spe
23、cification of individual languages, language variants, and language groups. The identifiers may be used in a variety of applications, including specification of the language used in a text, the language of terms or words in a dictionary or terminological database, the language used in a spoken prese
24、ntation, language proficiency, language capabilities of software, localization, etc. The various parts of ISO 639 are expected to be implemented in a number of environments. Parts 1, 2, 3, and 5 of ISO 639 all contain some information about implementation issues. However, it is deemed necessary to e
25、xpand those descriptions, and to have the implementation rules in a separate document. In future revisions of the other parts of ISO 639, it is expected that those standards will reference this part of ISO 639 rather than duplicating the information.

27、anguage coding using the codes that are specified in the other parts of ISO 639 and their combination with other codes. Furthermore, this part of ISO 639 lays down guidelines for the use of any combination of the parts of ISO 639. The terminology and general descriptions of this part of ISO 639 are
28、intended to replace corresponding text of other parts of ISO 639 as relevant in future revisions. Relevant metadata for the description of linguistic entities are also given, as a framework for databases of linguistic data to support the ISO 639 series of International Standards. 2 Normative referen

In future versions o
37、f other parts of ISO 639, it is expected that some or all of the terms and definitions will be replaced by a reference to the terms and definitions in this part of ISO 639. NOTE The definitions in this part of ISO 639 are intended for practical use within the context of the various parts of ISO 639
38、and their applications. For various linguistic purposes, there are needs for more detailed, and possibly deviating, definitions. 3.1 code data transformed or represented in different forms according to a pre-established set of rules NOTE The usage of the term “code” is not uniform in all standardize
39、d coding systems. According to the usage that is defined in this part of ISO 639, a “code” is to be understood as a code table (3.2) and the set of rules relating to the code table. Each individual row in a code table is a code element (3.4) (e.g. “de - German - allemand - Deutsch” in Part 1 of ISO
40、639), while the item “de” is the language identifier (3.5). 3.2 code table table of code elements (3.4) as part of a code (3.1) 3.3 code space totality of possible values for a set of identifiers within a code (3.1) EXAMPLE All sequences of two letters (az) form the code space of the alpha-2 languag
41、e code as specified in part 1 of ISO 639. NOTE The alpha-3 language codes that are specified in parts 2, 3, and 5 of ISO 639 share the same code space, i.e. no language identifier assigned in one of the parts may be assigned to a different item in another part.

43、 purpose of uniquely representing it NOTE 1 In the language codes of Parts 1, 2, 3, and 5 of ISO 639, each language identifier is composed of two or three letters.
