OData SDK Released

OData is a protocol for exchanging structured data sets in an interoperable fashion. The .Net implementation of OData is called WCF Data Services but the team has also released a variety of client libraries for other platforms in a package called the OData SDK. Included are libraries for Javascript, PHP, Java restlets, Windows Phone, and Objective C. The SDK also has samples for hosting services, a data explorer, and performing data validation.
