Annotations-Schema
Aktualisiert: November 2007
In diesem Thema wird die XML-Schemadefinition (XSD) beschrieben, die vom Microsoft Annotations Framework zum Speichern und Abrufen von Anmerkungsdaten von Benutzern verwendet wird.
Das Annotations Framework serialisiert Anmerkungsdaten von einer internen Darstellung eines XML-Formats. Das für diese Konvertierung verwendete XML-Format wird vom Annotations Framework-XSD-Schema beschrieben. Das Schema definiert das implementierungsunabhängige XML-Format, das verwendet werden kann, um Anmerkungsdaten zwischen Anwendungen auszutauschen.
Die Annotations Framework-XML-Schemadefinition besteht aus zwei Teilschemata:
Annotations XML Core-Schema (Core-Schema)
Annotations XML Base-Schema (Base-Schema)
Das Core-Schema definiert die primäre XML-Struktur einer Annotation. Die Mehrheit der XML-Elemente, die im Core-Schema definiert wird, entspricht Typen im System.Windows.Annotations-Namespace. Das Core-Schema macht drei Erweiterungspunkte verfügbar, an denen Anwendungen ihre eigenen XML-Daten hinzufügen können. Diese Erweiterungspunkte schließen Authors, ContentLocatorPart und "Content" ein. (Content-Elemente werden als XmlElement-Liste bereitgestellt.)
Das in diesem Thema beschriebene Base-Schema definiert die Erweiterungen für den Authors-Typ, den ContentLocatorPart-Typ und den Content-Typ, die in der ursprünglichen Windows Presentation Foundation (WPF)-Version enthalten sind.
Dieses Thema enthält folgende Abschnitte:
Annotations XML Core-Schema
Annotations XML Base-Schema
Von Annotations XmlStreamStore erstelltes Beispiel-XML
Annotations XML Core-Schema
Das Annotations XML Core-Schema definiert die XML-Struktur, die verwendet wird, um Annotation-Objekte zu speichern.
