XTreeNet: scalable overlay networks for XML content dissemination and querying (synopsis)

XML is becoming a ubiquitous format for information exchange on the Internet. To alleviate the problems of "whom to ask" and "whom to tell" when connecting XML information producers with consumers over the network, content-based querying and dissemination of information have been investigated in the literature. Our XTreeNet project unifies the publish/subscribe and query/response models with a single common XML aware overlay network for XML-based information producers and consumers. This integrated framework lends itself to a variety of applications.
