[41] [[Web]] における [DFN[[[Notifications API]]]] は、[[著者]]から[[利用者]]に対する[[通知]]のための
[[API]] です。 [DFN[[CODE(DOMi)@en[[[Notification]]]]]] [[オブジェクト]]は[[通知]]を表します。

* 歴史

** [CODE(DOMm)@en[showNotification]]

[38] 2008年5月、 [[OS]] が[[通知]]の仕組みを提供するのが一般的になってきていたことや [[Google Gears]] [SRC[>>36]]
や [[Opera Widgets]] [SRC[>>32, >>33]] のように [[Web]] にもこれを持ち込む動きが出てきたことを受け [SRC[>>34]]、
[[HTML5]] に [DFN[[CODE(DOMm)@en[[[showNotification]]]]]] [[API]] が追加されました [SRC[>>28]]。
この [[API]] は[[平文]]の[[通知]]に対応していました。

[39] しかし [[Google Gears]] は[[平文]]ではなく [[HTML]] による[[通知]]を望んでいたこと、
他の [[Webブラウザー]]が実装の意思を示さなかったことから、 [CODE(DOMm)@en[[[showNotification]]]]
は削除されました [SRC[>>31, >>27]]。 [[Ian Hickson]] は、 [[HTML]] の[[通知]]は[[プラットフォーム]]側の[[通知]]
[[API]] と統合できなくなることを指摘し、複数の実装者が興味を示さない限り (Ian により)
仕様に含めることを拒んでいます [SRC[>>37]]。それに対し [[Mike Smith]] は [[W3C]]
での標準化を提案しており、これが [[Web Notifications WG]] へとつながったようです。
