Abstract

Many of the emergent digital ecosystems will employ sensor networks to generate data. Using XML to introduce structure and semantics assists the ecosystem as standard XML query languages such as XPath and XQuery are used to extract information and results of analyses. However, the creation of XML digital archives is hindered by the performance of these query languages. Furthermore, the multi-disciplinary nature of digital ecosystems means that knowledge workers and end users will rarely be IT professionals and therefore, unable to express XPath or XQuery easily. In this work, we present a method for precomputing and storing query results, leading to far higher levels of performance and removing the requirement for non-IT users to learn complex query languages.
