HYPERDAQ - WHERE DATA ACQUISITION MEETS THE WEB

HyperDAQ was conceived to give users access to distributed data acquisition systems easily. To achieve that, we marry two well-established technologies: the World Wide Web and Peer-to-Peer systems. An embedded HTTP protocol engine turns an executable program into a browsable Web application that can reflect its internal data structures using a data serialization package. While the Web is based on static hyperlinks to destinations known at the time of page creation, HyperDAQ creates links to data content providers dynamically. Peer-to-Peer technology enables adaptive navigation from one application to another depending on the lifetime of application modules. Traditionally, distributed systems give the user a single point of access. We take a radically different approach. Every node may become an access point from which the whole system can be explored.
