Abstract :
Triggered by the increasing number of internet user, the growing digitalization of physical information as well as the web 2.0 phenomenons, in recent years more and more data are becoming available on the web. RFID is used to digitalize information from the physical world, organizations (especially e-commerce provider) open their databases to the public via web services or APIs, and internet user enter a variety of personal and non-personal information. By combining this data via mash-ups or composed services, value is added and more complex, individualized, or richer information is generated.
