注釈スキーマ

  • [アーティクル]

このトピックでは、ユーザー注釈データを保存および取得するために Microsoft Annotations Framework によって使用される XML スキーマ定義 (XSD) について説明します。

Annotations Framework は、内部表現から XML 形式に注釈データをシリアル化します。 この変換に使用される XML 形式は、Annotations Framework XSD スキーマによって記述されます。 スキーマでは、アプリケーション間で注釈データを交換するために使用できる、実装に依存しない XML 形式を定義します。

Annotations Framework XML スキーマ定義は、2 つのサブスキーマで構成されます

  • アノテーションXMLコアスキーマ（コアスキーマ）。

  • アノテーション XML 基本スキーマ (基本スキーマ)。

コア スキーマは、Annotationのプライマリ XML 構造を定義します。 コア スキーマで定義されている XML 要素の大部分は、System.Windows.Annotations 名前空間の型に対応しています。 コア スキーマは、アプリケーションが独自の XML データを追加できる 3 つの拡張ポイントを公開します。 これらの拡張ポイントには、Authors、ContentLocatorPart、および "コンテンツ" が含まれます。 (コンテンツ要素は、XmlElement リストの形式で提供されます)。

このトピックで説明する基本スキーマでは、Windows Presentation Foundation (WPF) の初期リリースに含まれる Authors、ContentLocatorPart、およびコンテンツ タイプの拡張機能を定義します。

Annotations XML Core Schema は、Annotation オブジェクトの格納に使用される XML 構造を定義します。
