Description

This method is used to define the structure of the metadata that is written during synchronization. It is called once for each property of the dataset during synchronization. The method requires three parameters; pPropertySet, itemDesc, and Value.

Remarks

The pPropertySet parameter is an XML property set representing the metadata of the dataset being synchronized.

The itemDesc string parameter describes what object is being passed in the Value parameter.

The Value parameter  is an object of the data sets whose metadata is being synchronized.

The different objects passed to the Update method, the Value parameter, vary from type of data set that is being synchronized. Not all itemDesc are supported for all data types. For instance CoverageEntity objects only apply to ArcInfo coverages and ArcInfo tables.

A complete list of the expected Values for the supported itemDesc items is available in the Technical Paper "Creating a Custom Metadata Synchronizer", May 2001.
