The document explores the concept of the programmable web and how ASP.NET 'Atlas' facilitates the creation of mash-ups and data-sharing applications. It covers the importance of reusing data from multiple services, demonstrates the music mix application as a mash-up, and introduces gadgets as user interface solutions. Additionally, it highlights the need for user-driven mash-ups and structured data sharing through a web clipboard model.

4. What Is The Programmable Web Transformation of the Web from content publishing medium into a platform Each application is a component in this platform Enable sharing and unlocking user and application data Via services and APIs, data formats and schemas Applications and Scenarios Mash-ups Services (REST, SOAP, RSS, …) Shared components (eg. Gadgets) Shared data formats (eg. Live Clipboard)

5. Consuming the Programmable Web Mash-ups Applications that re-mix or aggregate data from one or more services to create new end-user experiences and scenarios How do they work? Link to one another via shared data semantics Bring and co-relate data for end-users into one location Why build mash-ups? Leverage the power of the Web platform Create rich and immersive user experiences Meet a new bar of growing user expectations

18. Abstract This session explores the programmable Web, and how ASP.NET “Atlas” enables applications to easily participate in this new platform via mash-ups and other forms of data sharing. The presentation explores key mash-up concepts, and demonstrates leveraging data from services such as MSN Search, and Amazon Web Services in a reusable and component oriented fashion. Secondly, it demonstrates how an application can expose data via services, APIs and reach end-users with its services via Windows Live Gadgets. Finally it provides a glimpse of enabling user-driven mash-ups and copy/paste of structured data by implementing a clipboard model for the Web.
