Objective
The project aims to develop a next generation system for XPath and XQuery processing that integrates efficient XPath processing techniques in an algebraic XQuery processor, performs algebraic query rewriting for XPath and XQuery, and supports distributed query evaluation over autonomous sources with potentially limited query capabilities.
Hence the project has two interrelated activities:
- the creation of a framework for the integration and evaluation of efficient XPath and XQuery processing techniques with different strengths and applicability profiles. In this context we aim to explore the applicability of existing techniques for XPath processing on relational systems to native systems and vice versa, to develop new processing techniques and to integrate them into an algebra-based XQuery processor that can apply them as needed based on heuristics we will develop.
- The development of a novel framework for the distributed execution of XPath and XQuery over autonomous sources with limited capabilities that incorporates and combines the familiar notions of local and global as view processing. In order to do that we will clarify the semantics of sound views in the XML setting, develop a capability description languages for XML sources and design efficient techniques for XPath and XQuery composition and rewriting using views. The use of appropriate description logics is envisioned to capture constraints for XML data sources; the rewriting algorithms will take into account these constraints.
The overall aim is to create a flexible, modular, state of the art XQuery processor and mediator based on formal foundations that exploits, unifies and extends the significant but often fragmented advances made in XPath and XQuery processing, and uses new techniques f or answering XPath and XQuery using views.
