+    \class QMetaDataReaderControl
+    \ingroup multimedia-serv
+
+    \preliminary
+    \brief The QMetaDataReaderControl class provides read access to the
+    meta-data of a QMediaService's media.
+
+    If a QMediaService can provide read or write access to the meta-data of
+    its current media it will implement QMetaDataReaderControl.  This control
+    provides functions for both retrieving and setting meta-data values.
+    Meta-data may be addressed by the well defined keys in the
+    QtMultimedia::MetaData enumeration using the metaData() functions, or by
+    string keys using the extendedMetaData() functions.
+
+    The functionality provided by this control is exposed to application
+    code by the meta-data members of QMediaObject, and so meta-data access
+    is potentially available in any of the media object classes.  Any media
+    service may implement QMetaDataReaderControl.
+
+    The interface name of QMetaDataReaderControl is
+    \c com.nokia.Qt.QMetaDataReaderControl/1.0 as defined in
+    QMetaDataReaderControl_iid.
+
+    \sa QMediaService::requestControl(), QMediaObject
