Resource Description for End-User Driven Service Compositions

In the current web, end-users´ involvement on creating content for the modern web applications and participation on tailoring their own web applications is increasing. These applications are often called Personalized Web Tasks. Thus, in addition to software developers, end-users are now participating in the service development through personal service configurations. End-user driven development poses new requirements on the development tools, which traditionally are targeted for software developers. We discuss the requirements for end-user driven integration of data-oriented web resources and use our own prototype tool as an example implementation. We describe generic data types for web services and propose a technique for adding metadata to service descriptions. The metadata is used to help the user to build service configurations and to convert data between different formats used by web services.
