Microsoft releases the OData Helper for WebMatrix and ASP.NET Web Pages allows you to easily retrieve and update data from any service that exposes its data using the OData Protocol. Designed to make it easier to use OData services in your WebMatrix website. The OData is open sourced and is available on CodePlex for download, use, explore and also contribute to.
"OData, is an open specification that makes it possible to have consistent APIs for all different services out there. Effectively it's REST with a powerful query syntax that makes it easy to extract the data you want from a service. So far there're a bunch of websites that've exposed their data using the spec, including Facebook, Netflix, Stackoverlow etc. There's a full list over here as well as more information on the spec itself."
