Annotation Elements (CSDL) Conceptual Model Types (CSDL) Facets (CSDL) Conceptual schema definition language (CSDL) is an XML-based language that describes the entities, relationships, and functions that make up a conceptual model of a data-driven application. This conceptual model can be used by the Entity Framework or WCF Data Services.
