For getting useful and lively information, subscribers can choose a primary application and pick the interesting parts from other source applications. By using XML Object as the event container to encapsulate any types of the message, we achieve the flexibility of content definition, self-contained data description, and high portability. According to the content syndication profiles, the information from source applications will create relationship and all the matching and useful events in target XML Object will be sent to subscribers periodically. With attachment XML Object, the levelly text/multimedia contents from related source applications can be embedded into target XML Object.
