[62] Web IDL は、 DOM その他の API の記述に使われる言語です。 仕様書としての Web IDL には、その言語自体の定義に加え、 Web IDL の記述と JavaScript の処理との対応関係や、 Web における JavaScript の API として実装するべき機能が規定されています。

仕様書

概念

[80]

  • module
  • sealed
  • exception

JavaScript 束縛

[63] DOM API は Web IDL によって定義されていて、 Web IDL と JavaScript の対応関係は Web IDL 仕様書で定義されています。

[64] いくつかの機能は Web IDL だけで記述できず、直接 JavaScript の概念を参照して定義されています。

互換性

[59] 記述言語としての Web IDL は不特定多数の著者が直接使う機能ではないので、 しばしば非互換変更が行われます。通常の Web 技術とは違って、 必要の無い機能は積極的に削除されます。

[60] Web IDL の改訂と Web IDL を使う各仕様の改訂は、必ずしも同期していません。 Web IDL に追加される見込みの (または追加してほしいと希望している) 機能が各仕様で使われることもあります。各仕様でまだ使われている機能が Web IDL から削除されることもあります。

歴史

W3C DOM 時代

[69] W3C DOM は OMG IDL を使っていました。各仕様書には附属書として Java束縛およびECMAScript束縛が規定されていましたが、 特に後者は曖昧でほとんど意味をなさないものでした。

HTML5

[70] WF2, WA1, XBL2 といった初期 WHATWG 世代の仕様書では、 一部例外的な機能について、 JavaScript でどのように実装するべきかの規定を含んでいました。 しかし IDL と JavaScript との基本的な対応関係が規定されていない以上、 曖昧なものとならざるを得ませんでした。 Ian Hickson は、 いずれそれを明確化する必要があると予定していました。
