DDEX Data Object Support

Data Designer Extensibility (DDEX) data object types represent data source objects from an external data source. They are proffered by DDEX Providers and rendered in the Visual Studio IDE using XML defined in the data object support schema file (DataObjectSupport.xsd).

DDEX object types serve five main roles, describing the following:

  • How to handle an enumeration request from the metadata API and convert it into the equivalent request using the underlying enumeration technology.

  • The data returned by the underlying enumeration technology in terms of an identifier and properties.

  • The type, identifier, and properties in a generic fashion, when this is required.

  • How to build a DSRef object from a given instance of the type.

  • Data-source-specific restrictions described in terms of generic restrictions, in cases where this is required.
