[90] [DFN[[[Packaged Web Applications]]]] ([DFN[[[Widgets]]]]、
[DFN[[RUBYB[Widgets 仕様族]@en[Widgets family of specifications]]]]、
初期の名称は [DFN[[[Widgets 1.0]]]])
は、 [[Web]] の技術をベースに [[ZIP]] によりパッケージ化した[[アプリケーション]]を規定するものです。

[91] [[W3C]] [[WebApps WG]] (当初は [[WAF WG]]) で仕様化されて [[W3C勧告]]になりましたが、
この分野では各社の独自形式が主流となり、ほとんど使われることがありませんでした。

* 仕様書

[REFS[
- [94] [CITE[WidgetSpecs - WEBAPPS]] ([TIME[2013-06-13 21:01:58 +09:00]] 版) <http://www.w3.org/2008/webapps/wiki/WidgetSpecs>
]REFS]

[95] >>94 にある複数の仕様書群で構成されています。

* 機能

[106] 次の機能が含まれていました。
[FIG(short list)[
- [[ZIP]] によるパッケージ化
-- [[ZIPファイルの署名]]
- [[XML]] ベースの設定ファイル
- [[フォルダー]]を使った[[地域化]]
- [[Widget Instance]]
- [CODE(DOMi)@en[[[Widget]]]] [[API]]
- [CODE(DOMi)@en[[[WindowWidget]]]]
- [CODE(DOMi)@en[[[WidgetStorage]]]]
- [CODE(URI)@en[[[widget:]]]] [[URL]]
- [CODE(HTML)@en[[[rel=widget]]]]
- [CODE(CSS)@en['[[view-mode]]']] [[媒体機能]]
]FIG]


* 実装

[108] 次の実装がありました。
[FIG(short list)[
- [[Opera]] ([[Presto]])
- [[NetFront Widgets]]
-- [[ソフトバンク]] [[モバイルウィジェット]]
- [[Tizen]] [[Web Runtime]]
]FIG]

[92] [[Opera]] が独自の [[Opera Widgets]]  にかわる新形式として実装しましたが、 [[Presto]] から [[Chromium]]
への移行により再実装されなかったようです。 (現在の [[Opera]] は [[Chrome拡張]]の形式を実装しています。)

[93] [[ACCESS]] の [[NetFront Widgets]] も [[Widgets 1.0]] に基づくもので、一部の[[ガラケー]]などが対応しています。

[110] [[Cordova]] は [[Widget]] の設定ファイルを流用していますが、
[[Widget]] の実装ではないようです。

* 歴史

** その後

[98] 結局 [[Widget]] 仕様は広く普及することはありませんでした。

[99] 後に [[ED]] が [[GitHub]] でも公開されていますが、そこには [[Widget]]
仕様群が放棄された旨が明記されています [SRC[>>97]]。

[100] [[W3C勧告]]として出版されたものは[[廃止]]手続きが取られたわけではないようですが、
既に実効性を失っています。 ([[W3C]] ではよくあることです。)

[101] [[Widget]] の開発者である [[Marcos Cáceres]] は、その後 [[Web App Manifest]]
の開発に取り組んでいます。 [[ZIP]] ファイルにまとめて配布しなければならない [[Widget]]
とは異なり、 [[Web App Manifest]] は既存の [[Webサイト]]に[[マニフェスト]]ファイルを付け足して[[メタ情報]]を記述するだけでも使えます ([[ZIP]] として配布することもできます)。
[[Web App Manifest]] では独自の実行環境ではなく、通常の [[Web]]
の実行環境をほぼそのまま使います。

> Apache Cordova applications rely on a common config.xml file that provides information about the app and specifies parameters affecting how it works, such as whether it responds to orientation shifts. This file adheres to the W3C's Packaged Web App, or widget, specification.

[FIG(data)[ [115] [[HTML要素概説]]

-
[DFN[Widgets]]
[[W3C WAF WG]] で開発された仕様群。
[[HTML]] 等を [[ZIP]] ファイルにまとめた小型アプリケーションの実行環境で、
[[Opera]] や一部の[[ガラケー]]などが実装していた。
商業的に成功しなかったが、後に [[Web App Manifest]] に間接的につながる。
