The main configuration file is called wimconfig.xml. This file stores the virtual member manager settings at the global (admin) level or at the domain level in a multiple security domain environment.
The wimdomain.xsd file contains the “data model” of virtual member manager. It consists of the definitions of the entity types that virtual member manager supports out-of-the-box. The wimdomain.xsd is the detailed XML Schema representation of the virtual member manager common data model. The properties for the entity types are defined at the virtual member manager level and need to be mapped to actual repository-specific property definitions in other configuration files.
The wimdatagraph.xsd file defines the options that can be specified when the virtual member manager API is invoked.
If you need to extend the virtual member manager domain model to add more entity types or properties for the out-of-the-box entity types, you must use a separate XSD file (for example, wimextension.xsd) or a separate XML file (for example wimxmlextension.xml).
