href="/wiki/ISO_3166" title="ISO 3166">ISO 3166</a> in 1974, the first edition of the standard ISO 639:1988 <i>Code for the representation of names of languages</i> was published with a framework of uniformly two-letter identifiers in lowercase Latin alphabets, mostly identical in format and vocabulary to that of the current ISO 639 Set 1. </p><p>Since then, the standard has been adopted as a fundamental technology of the rapidly expanding computer industry (<a href="/w/index.php?title=RFC_1766&action=edit&redlink=1" class="new" title="RFC 1766 (page does not exist)">RFC 1766</a>), leading to development of more expressive three-letter framework, published as ISO 639-2:1998, largely based on <a href="/wiki/MARC_standards" title="MARC standards">MARC</a> codes for languages. The original two-letter system was redefined as ISO 639-1 in 2001. </p><p>Seeking for more extensive support of languages for widening applications, separate supersets of the ISO 639-2 namespace that cover individual languages and groups were established as ISO 639-3 and ISO 639-5, respectively. There was also an attempt to code more precise language variants using four-letter identifiers as ISO 639-6, which was later withdrawn and to be reorganized under another framework, <a href="/w/index.php?title=ISO_21636&action=edit&redlink=1" class="new" title="ISO 21636 (page does not exist)">ISO 21636</a>. </p><p>Relatively constant updates in parts of ISO 639 had been handled by each own authority in charge until the publication of ISO 639:2023, which harmonized and reunified the body text of former standards and brought about organizational change with a joint maintenance agency supervising all sets and issuing newsletters.

However, not all languages are in all sets, and there is a variety of different ways that specific languages and other elements are treated in the different sets. This depends, for example, whether a language is listed in Sets 1 or 2, whether it has separate B/T codes in Set 2, or is classified as a macrolanguage in Set 3, and so forth. </p><p>These various treatments are detailed in the following chart. In each group of rows (one for each scope of Set 3), the last four columns contain codes for a representative language that exemplifies a specific type of relation between the sets of ISO 639, the second column provides an explanation of the relationship, and the first column indicates the number of elements that have that type of relationship. For example, there are four elements that have a code in Set 1, have a B/T code, and are classified as macrolanguages in Set 3. One representative of these four elements is "Persian" <code>fa</code>/<code>per</code>/<code>fas</code>. <style data-mw-deduplicate="TemplateStyles:r1245584064">@media screen{html.client-js
