Abstract: The claimed subject matter provides for an online, Internet-class service that can correlate between an application interface utilizing a highly expressive, EDM conceptual format and a data store structured in an efficient, highly scalable storage format. Such a service can include components that map between an EDM schema and a data structure format. Additionally, a query reply can include data presented with a payload format distinct from an EDM query format.

Abstract: The claimed subject matter provides a representational state transfer (REST) interface over a data store characterized by an entity data model (EDM) architecture. Such characterization can be presented by way of an Entity Framework that can transform data characterized in one manner at a relational database into an EDM characterization that can further be exposed to an external process or device. A REST interface over EDM stores can provide an end-to-end framework to expose data, modeled in a highly-expressive fashion, to the Internet or a web-scale intranet.
