XTreeNet: Scalable Overlay Networks for XML Content Dissemination and Querying

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.
