Extend virtual member manager functionality in the application

The virtual member manager model extension framework enables you to extend the virtual member manager model both at deployment time and at runtime.

Although virtual member manager comes with a built-in model, you might need to add new property definitions, new entity types and new control types to satisfy your specific needs.

The format (model) of the data graph can be expressed either as a dynamic model (XSD) or a static model (statically-generated code).

Properties and entities in the same name space must be either all in the static model or all in the dynamic model. The models cannot be mixed in the same name space.

The scope of extension includes adding at runtime and at deployment time. Virtual member manager is based on Service Data Object (SDO). The virtual member manager data graph model can be either static or dynamic. Static means code has been generated at deployment time to implement the model; dynamic means no code has been generated and the model is built in memory by loading from XSD files during each startup.

The performance of the static model is better but the dynamic model is more flexible.

The virtual member manager model extension framework supports the following scenarios where virtual member manager is configured to use:
