SINN and XQuery: Results and Implementation

Abstract:

To build an open, standardized, load-balanced and scalable network of scientific search engines, this is the goal of SINN. Open means, that the software should be free to use for science and education. The network should be using standardized protocols for communication between the participants. A first implementation of this network using W3C's XML-Query standard is presented. This network allows searching across several data-repositories, e.g. Harvest brokers even on high loaded networks. Data-Providers can register themselves to answer queries or unregister, when load has reached their maximum level. Off runtime of answering queries data-providers can share their indexes,increase redundancy. This networks allows the user to use the full functionality of XML-Query. A short overview over this programming language-like query language is also given.
