Last week David Treadwell's blog posting on Windows Live had some very interesting news. In particular, Web3S was replaced by Atom/AtomPub and a bunch of new Live services will use it right away, as well as tooling support. I can imagine the pain that my past colleague Yaron is feeling, but it really is the right thing. It will be interesting to see how they solved one of the big problems still in Atom that was solved in Web3S, which is doing Partial updates.
This part of the announcement is:
Microsoft is making a large investment in unifying our developer platform protocols for services on the open, standards-based Atom format (RFC 4287) and the Atom Publishing Protocol (RFC 5023). At MIX we are enabling several new Live services with AtomPub endpoints which enable any HTTP-aware application to easily consume Atom feeds of photos and for unstructured application storage (see below for more details). Or you can use any Atom-aware public tools or libraries, such as .NET WCF Syndication to read or write these cloud service-based feeds.
In addition, these same protocols and the same services are now ADO.NET Data Services (formerly known as " Project Astoria") compatible. This means we now support LINQ queries from .NET code directly against our service endpoints, leveraging a large amount of existing knowledge and tooling shared with on-premise SQL deployments.
The intent for these early, experimental releases are to gather valuable feedback from the community around our idiomatic and freely licensed extensions to AtomPub which deal with important service scenarios, such as URL formats, nested directories, image streams, and service metadata. You can read more about this on the Project Astoria team blog.
