Astoria is a Microsoft project geared toward Web APIs for data access. It makes heavy use of the ADO.NET Entity Framework data model, which is due for release in 2008.
This tipcast, based on an article called Microsoft Project Astoria brings data services to Web API battle, offers an introduction to this new data model and how it is able to leverage REST, the representational state transfer. The information comes to us courtesy of Julie Lerman, who delivered a talk on Astoria at the recent ReMIX07 Boston.

More on Astoria from around the Web
"The first Astoria CTP is a dual release, making Astoria available in the form of downloadable bits that can be used to build data services that are entirely contained within a single computer or network and as an experimental online service that you can use to create online stores that are hosted by Microsoft and are accessible over the internet. This September 2007 CTP is mostly a refresh of the past May 2007 that enables developers to use Astoria together with Visual Studio 2008 Beta 2 and the ADO.NET Entity Framework and Tools Beta 2."
"Astoria exposes data as web services through an Entity Framework Data Model. Once exposed, you can use URI based syntax to query data through the conceptual layer of the entity data model. You can control what is and isn't exposed and you can also do inserts, updates and deletes. The results can be output in a number of formats including JSON and ATOM."
