ISO 639-5:2008 言語の名前を表現するためのコード — Part 5: 言語族およびグループのためのAlpha-3コード | ページ 2

Foreword

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 committees. 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 the 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, 2.

The main task of technical committees is to prepare International Standards. Draft International 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 the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

ISO 639-5 was prepared by Technical Committee ISO/TC 37, Terminology and other language and content resources, Subcommittee SC 2, Terminographical and lexicographical working methods.

ISO 639 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: Implementation guidelines and general principles for language coding
• Part 5: Alpha-3 code for language families and groups
• Part 6: Alpha-4 code for comprehensive coverage of language variants

Introduction

ISO 639 provides codes for the identification of languages, language variants, and language groups. The identifiers may be used to denote the language used in a text, the language of terms or words in a dictionary or terminological database, the language used in a spoken presentation, language capabilities of software, etc.

ISO 639-2 includes some language groups and language families, but by no means a complete list. The purpose of the code elements for language groups and language families in ISO 639-2 is to provide a means to register the language of a document even when the individual language in question is not included in the code table. This part of ISO 639 supplements the coding of language groups and language families in ISO 639-2. However, the depth and detail of coding in this part of ISO 639 is intended to support the overall language coding of the ISO 639 series of International Standards rather than provide a scientific classification of the languages of the world.

The list of language families and groups in this part of ISO 639 will be extended and developed continuously through a defined maintenance process.

1 Scope

This part of ISO 639 provides a code consisting of language code elements comprising three-letter language identifiers for the representation of names of living and extinct language families and groups. Languages designed exclusively for machine use, such as computer-programming languages, are not included in this code.
