Finally Astoria coming to your SharePoint Theatres
Do you remember my Astoria Blog Publishing post? well now you can check that my crystal ball is up and running!
Cool to see that any SharePoint Server 2010 acts as a Data Services Server
So moving forward that vision would look like this, after installing latest ADO.NET Data Services in your SharePoint 2010 sandbox, imagine you create a blog site /carloshm, then you will be able to get the categories at /carloshm/_vti_bin/ListData.svc/Categories. That simple.
