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。




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。


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。



World Wide Web Consortium(W3C)は、Web標準化の開発を目的とし、会員組織、フルタイムスタッフ、および公的団体が連携する国際的なコンソーシアムです。W3Cは、Webの長期的な成長の確保を目的としたWeb標準およびガイドラインの作成を通じ、使命に尽力しています。Open Web Platformは、現在、我々が最も注力している分野です。400を超える組織が、本コンソーシアムの会員として参加しています。W3Cは、米国MIT Computer Science and Artificial Intelligence Laboratory(MIT CSAIL:マサチューセッツ工科大学計算機科学人工知能研究所)、フランスEuropean Research Consortium for Informatics and Mathematics(ERCIM: 欧州情報処理数学研究コンソーシアム)、日本の慶應義塾大学、及び中国の北京航空航天大学 (Beihang University)により共同運営されており、各国にW3Cオフィスを設置しています。詳細については、http://www.w3.org/をご覧ください。

2014年、W3Cは、W3C20周年、およびTim Berners-Leeが発明したウェブ25周年という二つの記念式典を挙行します。

Intel strongly supports the power of cross-platform development enabled by HTML5 for both application and website development. We know developers are constantly pushing to maximize revenue by publishing apps that work across multiple screen sizes and operating systems, and HTML5 tools allow them do that while reducing development costs and time to market. Intel recognized this need early, and we are investing in standards development at W3C and software such as the Crosswalk project and Intel XDK that help developers take full advantage of HTML5.

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


NTT is delighted that HTML5 has finally came up to the stage of recommendation and we would like to express our great respect to the many people who were involved. Not only is this recommendation one of the historic milestones for the information and communications technology, but also we expect this is the next starting point of further progress of the web platform for the whole world. We are willing to join to enhance possibilities of the power of the web through our services from now on too.

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.

Mike Paciello, Founder The Paciello Group (TPG)


HTML5 represents to us a stable cross-platform technology for interactive applications which we support in our applications. Profium would like to thank those in and outside of W3C who have contributed to the development effort.

Janne Saarela, CEO, Profium
