OData: There’s a feed for that
I am spending a lot of time on the Open Data Protocol (OData).
Many of us at Microsoft that believe that this protocol can help usher in a more open and programmable Web.
A protocol like this is a prerequisite for the broader “Infobus” and “Information Liberation” vision that I often talk about.
Envision a world where every application/Web property exposes its data (actually your data) in a way that you can easily query it in rich tools like Excel/Numbers or write your own mash-up/custom application.
