[2] [DFN[[CITE[HTML]]]] あるいは [DFN[[CITE[HTML Standard]]]]、 [DFN[[CITE[HTML Living Standard]]]] 
は、 [[Web platform]] の中核部分をなす [[HTML]] や [CODE(DOMi)@en[[[Window]]]]、
その他各種周辺技術を規定する[[仕様書]]です。

[41] [CITE[HTML Standard]] は、 [[W3C]] が [[HTML]] の標準化を放棄した後 [[Ian Hickson]] が
[[WHATWG]] で出版してきた [CITE[[[Web Applications Markup Language 1.0]]]] → 
[CITE[[[Web Applications 1.0]]]]
→ [CITE[[[HTML 5]]]] → [CITE[[[HTML5]]]] → 
[CITE[[[Web Applications 1.0]]]] →
[CITE[[[HTML5 (including next generation additions still in development)]]]]
の流れを引く最新の [[HTML]] の仕様書です。

[146] 
[TIME[西暦2003年][year:2003]]以来現在に至るまで継続的に改訂されており、
[[Web]] の進化を牽引しています。

* 仕様書

[REFS[
- [1] [CITE@en-US-x-hixie[HTML Standard]] 
<http://www.whatwg.org/specs/web-apps/current-work/>
]REFS]

* 開発体制

[57] 他の [[WHATWG]] の[[仕様書]]同様、 [[Living Standard]] モデルで
[[GitHub]] を使って開発されています。

;; [[WHATWG]] 参照。

[58] 2003年の前身仕様書以来、時期にもよりますが、かなりの高頻度で更新されています。
2016年現在、日に数回の頻度で改訂が続けられています。

* 内容

[43] [[HTML]] は膨大な技術の集合体であり、必然的に [[HTML Standard]] 
の内容も多岐にわたっています (これは「キッチンシンク」といわれています)。
次に示すのはその一部です。

* 関連

[48] [[W3C]] は [[HTML 5.0]] や [[HTML 5.1]] を出版していますが、これらは
[[WHATWG]] [[HTML Standard]] の過去の版から派生し、数日から数週間遅れで [[WHATWG]]
[[HTML Standard]] の変更に追随したり、独自の編集を加えたりしているものです。
[[Ian Hickson]] は、 [[W3C]] の行為は[[剽窃]]であると非難しています。

[147] 
その後 [[W3C]] はこの活動を断念し、 [[WHATWG]]
に協力することに合意しました。 
[SEE[ [[HTML 5.3]] ]]

** HTML5 から HTML Standard へ

[3] [CITE[Web Applications 1.0]] が
[TIME[2007年5月][2007-05]]に [CITE[HTML5]] (当初は [CITE[HTML 5]]) に改称された後、
[TIME[2009年10月][2009-10]]には 
[[WHATWG]] で [[LC]] 状態に達しました。この頃まで [[WHATWG]] は [[HTML5]]、
[[Web Workers]] など複数の仕様書を出版していましたが、
[TIME[2009年10月][2009-10]]には再び
[CITE[Web Applications 1.0]] という名称でこれらすべてを統合した仕様書を (単体の仕様書とは別に)
出版するようになりました。
[SEE[ [CITE[Web Applications 1.0]] ]]

[4] その後
[TIME[2010年1月][2010-01]]までに 
[[WHATWG]] は [[HTML'''5''']] という特定の版の [[HTML]] 仕様のメンテナンスを放棄し、
版番号の無い最新の「[[HTML]]」を仕様化してゆく方針を固めますが、認知や検索性の問題から
「[[HTML5]]」という単語が好まれたため、この時は [CITE[HTML5]] が
[DFN[[CITE[HTML5 (including next generation additions still in development)]]]] 
に改称されるにとどまりました。

;; [53] [TIME[2009年12月][2009-12]]に
「[[HTML5]] 後の最初の新要素」として [CODE(HTMLe)@en[[[device]]]]
[[要素]]が追加されました。 [SEE[ [CODE(HTMLe)@en[device][<device>]] ]]

[5] しかし[TIME[2011年1月][2011-01]]に 
[[W3C]] が [[CSS3]] や各種 [[Web API]] など広範囲の [[Web]] 関連技術を
「[[HTML5]]」と呼んで広報活動を展開したことにより、 [[HTML5]] が完全に[[バズワード]]と化したことから、
本来 [[HTML]] と呼ばれるべき中核部分の仕様書である
[CITE[HTML5 (including next generation additions still in development)]] は [CITE[HTML]]
と改称されました。 
文脈上曖昧な場合には、[[小見出]]しより 
[[HTML Living Standard]] と呼ばれるようになりました。
なお Web 開発者向けに編集した Web Developer Edition は引き続き [[HTML5]] とされました。

[6] [TIME[2011年10月][2011-10]]には [CITE[HTML]] が [CITE[Web Applications 1.0]] と統合され、 [[WHATWG]]
の全体の仕様書の名称が [CITE[HTML]] ([[HTML Living Standard]]) となりました。

- [21:49] <Hixie> what was called Web Apps 1.0 originally, many years ago, was at one point renamed HTML, then things were dropped from it to track the w3c, eventually they dropped so much that we added a separate spec at the whatwg to include everything again, and called it Web Apps 1.0 for nostalgic reasons
- [21:50] <Hixie> and today i got tired of having two specs at whatwg (it makes various things annoying and some of our tools are overloaded by it) and so i just went back to the state after the first time we renamed the spec
