Databases and networks currently have different service models. Database services are data-centric in that users typically describe the content of data and the system finds and returns matching data. However, traditional Internet services are server-centric in that users have to know the location of data (e.g., a URL) in order to retrieve it. The authors envision a future in which Internet services are data-centric. Users specify their interests and publishers describe their data. Based on the matching between user interests and data contents, users can pull data from publishers, and publishers can push data to interested users.
