IETF Language Tag
An IETF BCP 47 language tag is a standardized code or tag that is used to identify human languages in the Internet. The tag structure has been standardized by the Internet Engineering Task Force (IETF) in ''Best Current Practice (BCP) 47''; the subtags are maintained by the ''IANA Language Subtag Registry''. To distinguish language variants for countries, regions, or writing systems (scripts), IETF language tags combine subtags from other standards such as ISO 639, ISO 15924, ISO 3166-1 and UN M.49. For example, the tag "en" stands for English; "es-419" for Latin American Spanish; "rm-sursilv" for Romansh Sursilvan; "sr-Cyrl" for Serbian written in Cyrillic script; "nan-Hant-TW" for Min Nan Chinese using traditional Han characters, as spoken in Taiwan; and "gsw-u-sd-chzh" for Zürich German. In its accordance with ISO 639-3, however, it does not provide codes for distinguishing between Arabic-based scripts, and maintains two duplicate codes for Punjabi, as well as a numb ...

Language
Language is a structured system of communication. The structure of a language is its grammar and the free components are its vocabulary. Languages are the primary means by which humans communicate, and may be conveyed through a variety of methods, including spoken, sign, and written language. Many languages, including the most widely-spoken ones, have writing systems that enable sounds or signs to be recorded for later reactivation. Human language is highly variable between cultures and across time. Human languages have the properties of productivity and displacement, and rely on social convention and learning. Estimates of the number of human languages in the world vary between and . Precise estimates depend on an arbitrary distinction (dichotomy) established between languages and dialects. Natural languages are spoken, signed, or both; however, any language can be encoded into secondary media using auditory, visual, or tactile stimuli – for example, writing, whi ...

Southern Min
Southern Min (), Minnan (Mandarin pronunciation: ) or Banlam (), is a group of linguistically similar and historically related Sinitic languages that form a branch of Min Chinese spoken in Fujian (especially the Minnan region), most of Taiwan (many citizens are descendants of settlers from Fujian), Eastern Guangdong, Hainan, and Southern Zhejiang. The Minnan dialects are also spoken by descendants of emigrants from these areas in diaspora, most notably the Philippines, Indonesia, Malaysia, Singapore, San Francisco, Los Angeles and New York City. It is the most populous branch of Min Chinese, spoken by an estimated 48 million people in c. 2017–2018. In common parlance and in the narrower sense, Southern Min refers to the Quanzhang or Hokkien-Taiwanese variety of Southern Min originating from Southern Fujian in Mainland China. This is spoken mainly in Fujian, Taiwan, as well as certain parts of Southeast Asia. The Quanzhang variety is often called simply "Minnan Proper". It is ...

ISO 639-5
ISO 639-5:2008 "Codes for the representation of names of languages—Part 5: Alpha-3 code for language families and groups" is a highly incomplete international standard published by the International Organization for Standardization (ISO). It was developed by ISO Technical Committee 37, Subcommittee 2, and first published on May 15, 2008. It is part of the ISO 639 series of standards. Collective codes ISO 639-5 defines ''alpha-3'' (3-letter) codes, called "collective codes", that identify language families and groups. As of the February 11, 2013 update to ISO 639-5, the standard defines 115 collective codes. The United States Library of Congress maintains the list of Alpha-3 codes that comprise ISO 639-5. The standard does not cover all language families used by linguists. The languages covered by a group code need not be linguistically related, but may have a geographic relation, or category relation (such as '' Creoles''). Relationship to other parts of ISO 639 Some of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ISO 639-3
ISO 639-3:2007, ''Codes for the representation of names of languages – Part 3: Alpha-3 code for comprehensive coverage of languages'', is an international standard for language codes in the ISO 639 series. It defines three-letter codes for identifying languages. The standard was published by International Organization for Standardization (ISO) on 1 February 2007. ISO 639-3 extends the ISO 639-2 alpha-3 codes with an aim to cover all known natural languages. The extended language coverage was based primarily on the language codes used in the ''Ethnologue'' (volumes 10–14) published by SIL International, which is now the registration authority for ISO 639-3. It provides an enumeration of languages as complete as possible, including living and extinct, ancient and constructed, major and minor, written and unwritten. However, it does not include reconstructed languages such as Proto-Indo-European. ISO 639-3 is intended for use as metadata codes in a wide range of applications. ...

Grandfathered
A grandfather clause, also known as grandfather policy, grandfathering, or grandfathered in, is a provision in which an old rule continues to apply to some existing situations while a new rule will apply to all future cases. Those exempt from the new rule are said to have grandfather rights or acquired rights, or to have been grandfathered in. Frequently, the exemption is limited, as it may extend for a set time, or it may be lost under certain circumstances; for example, a grandfathered power plant might be exempt from new, more restrictive pollution laws, but the exception may be revoked and the new rules would apply if the plant were expanded. Often, such a provision is used as a compromise or out of practicality, to allow new rules to be enacted without upsetting a well-established logistical or political situation. This extends the idea of a rule not being retroactively applied. Origin Southern United States The term originated in late nineteenth-century legislation and ...

ISO 639-2
ISO 639- 2:1998, ''Codes for the representation of names of languages — Part 2: Alpha-3 code'', is the second part of the ISO 639 standard, which lists codes for the representation of the names of languages. The three-letter codes given for each language in this part of the standard are referred to as "Alpha-3" codes. There are 487 entries in the list of ISO 639-2 codes. The US Library of Congress is the registration authority for ISO 639-2 (referred to as ISO 639-2/RA). As registration authority, the LOC receives and reviews proposed changes; they also have representation on the ISO 639-RA Joint Advisory Committee responsible for maintaining the ISO 639 code tables. History and relationship to other ISO 639 standards Work was begun on the ISO 639-2 standard in 1989, because the ISO 639-1 standard, which uses only two-letter codes for languages, is not able to accommodate a sufficient number of languages. The ISO 639-2 standard was first released in 1998. In practice, ISO 639 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Portable Network Graphics
Portable Network Graphics (PNG, officially pronounced , colloquially pronounced ) is a raster-graphics file format that supports lossless data compression. PNG was developed as an improved, non-patented replacement for Graphics Interchange Format (GIF) — unofficially, the initials PNG stood for the recursive acronym "PNG's not GIF". PNG supports palette-based images (with palettes of 24-bit RGB or 32-bit RGBA colors), grayscale images (with or without an alpha channel for transparency), and full-color non-palette-based RGB or RGBA images. The PNG working group designed the format for transferring images on the Internet, not for professional-quality print graphics; therefore non-RGB color spaces such as CMYK are not supported. A PNG file contains a single image in an extensible structure of ''chunks'', encoding the basic pixels and other information such as textual comments and integrity checks documented in RFC 2083. PNG files use the file extension PNG or png and hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HTML
The HyperText Markup Language or HTML is the standard markup language for documents designed to be displayed in a web browser. It can be assisted by technologies such as Cascading Style Sheets (CSS) and scripting languages such as JavaScript. Web browsers receive HTML documents from a web server or from local storage and render the documents into multimedia web pages. HTML describes the structure of a web page semantically and originally included cues for the appearance of the document. HTML elements are the building blocks of HTML pages. With HTML constructs, images and other objects such as interactive forms may be embedded into the rendered page. HTML provides a means to create structured documents by denoting structural semantics for text such as headings, paragraphs, lists, links, quotes, and other items. HTML elements are delineated by ''tags'', written using angle brackets. Tags such as and directly introduce content into the page. Other tags such as surround ...

Hypertext Transfer Protocol
The Hypertext Transfer Protocol (HTTP) is an application layer protocol in the Internet protocol suite model for distributed, collaborative, hypermedia information systems. HTTP is the foundation of data communication for the World Wide Web, where hypertext documents include hyperlinks to other resources that the user can easily access, for example by a mouse click or by tapping the screen in a web browser. Development of HTTP was initiated by Tim Berners-Lee at CERN in 1989 and summarized in a simple document describing the behavior of a client and a server using the first HTTP protocol version that was named 0.9. That first version of HTTP protocol soon evolved into a more elaborated version that was the first draft toward a far future version 1.0. Development of early HTTP Requests for Comments (RFCs) started a few years later and it was a coordinated effort by the Internet Engineering Task Force (IETF) and the World Wide Web Consortium (W3C), with work later moving ...

Punjabi Language
Punjabi (; ; , ), sometimes spelled Panjabi, is an Indo-Aryan language of the Punjab region of Pakistan and India. It has approximately 113 million native speakers. Punjabi is the most widely-spoken first language in Pakistan, with 80.5 million native speakers as per the 2017 census, and the 11th most widely-spoken in India, with 31.1 million native speakers, as per the 2011 census. The language is spoken among a significant overseas diaspora, particularly in Canada, the United States, and the United Kingdom. In Pakistan, Punjabi is written using the Shahmukhi alphabet, based on the Perso-Arabic script; in India, it is written using the Gurmukhi alphabet, based on the Indic scripts. Punjabi is unusual among the Indo-Aryan languages and the broader Indo-European language family in its usage of lexical tone.
