+\title The QML Type System
+\brief Description of the QML type system
+
+The types which may be used in the definition of an object hierarchy in a QML
+document can come from various sources.  They may be:
+
+\list
+\li provided natively by the QML language
+\li registered via C++ by QML modules
+\li provided as QML documents by QML modules
+\endlist
+
+Furthermore, application developers can provide their own types, either by
+registering C++ types directly, or by defining reusable components in QML
+documents which can then be imported.
+
+Wherever the type definitions come from, the engine will enforce type-safety
+for properties and instances of those types.
+
+
+\section1 Basic Types
+
+The QML language has built-in support for various primitive types including
+integers, double-precision floating point numbers, strings, and boolean values.
+Objects may have properties of these types, and values of these types may be
+passed as arguments to methods of objects.
+
+See the \l{qtqml-typesystem-basictypes.html}{QML Basic Types} documentation for
+more information about basic types.
+
+\section1 JavaScript Types
+
+JavaScript objects and arrays are supported by the QML engine. Any standard
+JavaScript type can be created and stored using the generic \l var type.
+
+For example, the standard \c Date and \c Array types are available, as below:
+
+\qml
+import QtQuick 2.0
+
+Item {
+    property var theArray: new Array()
+    property var theDate: new Date()
+
+    Component.onCompleted: {
+        for (var i = 0; i < 10; i++)
+            theArray.push("Item " + i)
+        console.log("There are", theArray.length, "items in the array")
+        console.log("The time is", theDate.toUTCString())
+    }
+}
+\endqml
+
+See \l {qtqml-javascript-expressions.html}{JavaScript Expressions in QML Documents} for more details.
+
+
+\section1 QML Object Types
+
+A QML object type is a type from which a QML object can be instantiated. QML
+object types are derived from \l QtObject, and are provided by QML modules.
+Applications can import these modules to use the object types they provide.
+The \c QtQuick module provides the most common object types needed to create
+user interfaces in QML.
+
+Finally, every QML document implicitly defines a QML object type, which can be
+re-used in other QML documents.  See the documentation about
+\l{qtqml-typesystem-objecttypes.html}{object types in the QML type system} for
+in-depth information about object types.
