W3C

HTML5勧告–オープン・ウェブ・プラットフォームの重要なマイルストーンを達成

安定した基盤上で、次世代のウェブテクノロジーを構築



2014年10月28日(アメリカ): ワールド・ワイド・ウェブ・コンソーシアム(W3C)は、ウェブページやウェブアプリケーションを構築する際に使用されるフォーマットHTMLの第5版であるHTML5を勧告として公開し、オープン・ウェブ・プラットフォームの礎を築きました。HTML5は、アプリケーション開発者やアプリケーション産業がこの先何年に渡って信頼するに足る、アプリケーション開発のための機能を提供します。HTML5は今や幅広いデバイスで、そして世界中のユーザが利用可能であり、かつ豊富な機能を持つアプリケーションの開発コストを削減します。

W3Cディレクターを務めるティム・バーナーズ=リーは、「ビデオやオーディオをブラウザ上で見たり、ブラウザ上で通話をすることは、今や当然の事として受け止められている」と述べています。「写真や店舗の共有、ニュースの入手、情報の検索はどこからでも、どのデバイスからでも可能にすることを期待しています。HTML5とオープン・ウェブ・プラットフォームはユーザの更なる期待に応えます。」

HTML5は以下を含めた多様な新機能をもたらします:

広く利用されているHTML5

HTML5は何年にも渡り活用されています。 2014年VisionMobile社(英)の調査では、調査に協力したデベロッパの42%が、HTMLとCSS、JavaScriptの組み合わせをモバイル・アプリケーションの一部、或いは全てに使用していると発表しています。ガートナー(米)では、HTML5は2015年と2016年のモバイル技術や機能としてトップ10の一つであると述べ、「HTML5は、複数のプラットフォーム間でアプリケーションを提供する企業に取り不可欠な技術である」と伝えています。

2012年12月に、W3CがHTML5の仕様定義完了を発表してからの22ヶ月間、W3Cのコミュニティは「一度書けばどこでも展開可能」ということを保証するため、HTML5テストスイートに10万以上ものテストを追加しました。Test the Web Forwardのコミュニティは、現在もオープン・ウェブ・プラットフォームの相互運用性を推進すべく、継続的にその活動を続けています。

HTML5勧告では、60以上の企業がW3Cの特許方針の基に、ソフトウェアを実装する人達が使用料の支払いを必要としないロイヤリティフリーのライセンスに同意しています。ウェブ技術を使う開発者たちにとって使用料が発生しない事は、ウェブ・プラットフォームの進化を促進させる需要な事項でもあります。

次のステップ:開発者のアプリケーション基盤、ウェブの新しい応用事例

HTML5は既に開発者達に幅広く展開されていますが、W3Cはオープン・ウェブ・プラットフォームの名に基づき、既にその先を見据えて議論を重ねています。それはプラットフォームを超えたパワフルなアプリケーションの開発費を削減する事です。10月のW3Cブログ記事でW3C CEOのJeffrey Jaffeはこう述べています。「HTML5は完了した。W3Cは開発者がすぐにでも成功を収めるために、オープン・ウェブ・プラットフォームをより強化しなければならない。」それらの優先順位を実行するためには、「アプリケーション基盤を次世代のプラットフォームとして強化しなければならない。」と以下を挙げています。

W3Cはこれらの新しい枠組みを、今年は10月末に開催される例年の技術会議 (Technical Plenary Advisory Committee Meeting)で議論します。

数々の組織もW3Cの内外を問わず、毎日のように提案されているウェブの新しい機能を組み込む事を容易にしています。W3Cはペイメント(支払)、自動車、電子書籍、通信、エンターテインメントの各産業のユースケースに適応できるべく、その発展を進めています。それと同時に、4,500名のエンジニアが 180を超えるW3C Community GroupとW3C Business Groupにおいて新たな発想の基に活動を続けています。

謝辞

W3Cは、HTML5仕様の根幹を形造り、HTML言語に多大な影響力をもたらしたGoogleのIan Hickson氏に第一の感謝の意を表します。

またW3Cは、HTML Working Groupの共同議長であるMicrosoft社のPaul Cotton氏、IBMのSam Ruby氏、AppleのMaciej Stachowiak氏らの、HTML5を勧告まで完成させたリーダーシップとHTML Working Groupに対する数々の貢献に心より感謝致します。

また、W3Cは下記の方々にも謝辞を述べます。

Mozilla

It’s good to see HTML5 reach the Recommendation stage. We were one of the first organizations involved in HTML5 because we believe in continuing to evolve the open Web platform to support innovation and help users. We contributed many widely adopted technologies such as WebGL and helped pioneer technologies like WebRTC. We have also expanded the functionality of the Web on mobile through the use of WebAPIs, bringing Web app developers the power to access phone hardware. Many of these APIs are currently going through the standardization process. We’re now working with the W3C to help lead the work behind the HTML5 test suite, ensuring that tests can be run in an automated way, so that users and developers can benefit from more consistent behavior between browsers.

Andreas Gal, Chief Technology Officer, Mozilla

The Paciello Group

HTML5 is a great leap forward for an accessible web. In HTML5, accessibility is a core design principle. For the first time the semantics of HTML have been mapped, and implementation requirements defined in terms of the way HTML semantics are conveyed to people using assistive technologies. The addition of new interactive controls, native video and captioning, and new structural elements in HTML5, make it easier than ever for developers to create HTML interfaces that are usable by everyone. The inclusion of WAI-ARIA in HTML also provides developers with the tools and information to create accessible custom content and controls that extend the core features of HTML. The Paciello Group (TPG) is both proud and honoured to have contributed to the development of HTML5, but recognises that it is not an end in itself. HTML5 represents a very positive step in the evolution of the language of the web, and TPG welcomes the opportunity to continue contributing to its positive development.
