For Immediate
Release
2012年12月17日 - World Wide Webコンソーシアム (W3C)は、本日、HTML5およびCanvas 2Dに関する仕様策定完了を発表いたしました。これらの仕様は、現段階ではW3C標準ではないものの、現在各企業やデベロッパーが実装やプランニングに向けて安定的なターゲットを持つことができる、機能的に完成した・機能策定完了段階にあります。HTML5は、W3Cが推進するOpenWeb Platformの根幹を担っており、ビデオやアニメーション、グラフィクス、スタイル、タイポグラフィ、およびデジタルパブリッシング向けのその他ツール、ネットワーク機能拡張など、デバイス機能へのアクセスを行うクロスプラットフォームアプリケーションに対応するフルプログラミング環境です。
「ステークホルダーは、ウェブテクノロジーの広まりにともない、さらに安定した標準を望むようになっています。」W3C CEOのJeff Jaffeは、こう述べています。「現今、企業は、今後HTML5によって何ができるか、そして、今後顧客がどのようなことを要望してくるのかがわかっています。同じように、デベロッパーも、スマートフォン、車、テレビ、電子書籍、電子署名、あるいは、未知のデバイスなどと連携するためには、どのようなスキルを育成すべきなのか理解しています。」
また、W3Cは、本日、標準化の次のラウンドを視野に入れたHTML 5.1およびCanvas 2D, Level 2の第一草案も発表いたしました。W3Cコミュニティは、既存のHTML機能に加え、ビルトインHTML5アクセシビリティ、レスポンシブイメージ、およびアダプティブストリーミングを補完するための拡張機能など、新たな機能の開発を継続して強化していきます。
最新技術の躍進と活気あるブラウザ市場は、飛躍的なイノベーションを生み出す源です。また、これらの多くは、HTML5および関連技術を幅広く採用しています。最近実施された4000人以上のデベロッパーに対するKendo UI調査によると、63%超が「HTML5を積極的に開発している」という旨を示しています。しかし、同調査では、「ブラウザフラグメンテーション」は、テクノロジーの使用によるコストと複雑性が増加するため、依然としてデベロッパーの懸念事項となっていることも示されています。
W3Cは、ブラウザフラグメンテーションを低減し、HTMLを活用および作成するあらゆるツールへと実装を拡張することを目指して、相互運用性およびテストへ専念するW3Cの「Candidate Recommendation（勧告候補）」に着手しました。
W3C HTML Working Groupでは、本段階において、この仕様がブラウザ間での相互互換性、オーサリングツール、電子メールクライアント、サーバー、コンテンツマネージメントシステム、その他Webツールなどを確実に実現できるよう、さまざまなアクティビティを実施する予定です。HTML WGでは、現在のHTML5の実装を分析し、テスト開発の優先順位を定め、コミュニティと連携してこれらのテストに取り組みます。HTML WGでは、2014年中旬にこの実装フェーズを終了する計画であり、最終的なHTML5勧告の公開後には、W3CのPatent Policyに基づき、ロイヤリティフリーとして公開する予定です。
HTML WGだけが、HTML5およびOpen Web Platformの成功を追求しているわけではありません。たとえば、Web Performance Working Groupは、現在、パフォーマンスメトリクスへのアクセスを可能にする2つのW3C勧告を公開しており、Webアプリケーションパフォーマンスを評価および拡張するための技術を開発しています。最近では、November Workshop（2012年11月のワークショップ)でその技術を公表しています。Web and TV Interest Group（IG）およびCore Mobile Web Community Group（CG）は、増加する各種デバイスの展開を促進する手段として、テスト実施の優先順位を引き上げました。
本日発表した本仕様においては、多数のW3C会員の皆様、さまざまなコミュニティの皆様、そしてチームスタッフから多大な寄与をいただきました。
W3Cは、HTML5の歴史、ほぼすべてに携わってこられたEditor（エディター）であるGoogle社のIan Hickson氏に感謝申し上げます。
W3Cは、現在のHTML WGの共同議長であるMicrosoft社のPaul Cotton氏、IBM社のSam Ruby氏、Apple社のMaciej Stachowiak氏による本活動の推進に深く感謝いたします。また、W3C勧告に向かう仕様策定を導く支援をいただいている、現在のEditor(エディター)各位へも心から御礼申し上げます。
W3Cは、HTML WGに参加するすべての企業・組織・個人の皆様によって費やしていただいた多くの時間とエネルギーに、そして、今後の継続的なコミットメントに心から感謝を申し上げます。
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。375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)、および日本の慶應義塾大学により共同運営されており、各国のW3Cオフィス各国に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。

With the spread of smartphones, we consider HTML5 as the most promising application platform standards for realization of OS-independent services. However, the unique advantage of HTML5, which the other application platforms including OSs do not have, is cooperation and dispersability. This will become the driving force of the evolution of the future information system by promoting utilization of diverse services and devices. KDDI also offers a variety of smartphones to consumers. Through these terminals, we have already taken on a role to provide an HTML5 platform to the public.
Satoru Takagi, KDDI CORPORATION
HTML was born of the scientific community, and its importance to worldwide communication both within that community and to its myriad stakeholders is tremendous. As HTML5 and the Open Web Platform mature, Lawrence Berkeley National Laboratory sees new opportunities for facilitating open scientific collaboration, communicating discoveries, expanding the use of scientific computing, and bringing our tradition of teamwork to bear on the problems that challenge our world.
Annette Greiner, W3C Advisory Committee Representative, Lawrence Berkeley National Laboratory

Futomi Hatano, CTO, Newphoria Corporation
It is great news that HTML5 has reached CR status. It means almost all modern browsers will support HTML5 features themselves. This will not only drive the movement of developing Web services based on HTML5, but also lots of tools for HTML5 based site will also be deployed in the market. Of course, this is the not the last step toward the goal of building an Open Web Platform, but this is an important step.
Kensaku Komatsu, Research Engineer, NTT Communications
In 2003, when Opera started the spec that's now called HTML5, we dreamed that the Web would be the ubiquitous platform instead of the fragmented place it was then. Thanks to close co-operation with many others - some of whom are competitors - W3C is cementing the role of free, interoperable open standards at the heart of the world's communications network. Vive le Web.
Lars Erik Bolstad, VP Core Technology, Opera Software
