XML Reasoning: From Theory to Practice

Tuesday, November 25 2008 at 11:00AM
Salle de Conférence (Pavillon des Jardins)

In the research for XML static type systems, one challenge is to deal with XPath powerful navigational features. I will present a fixpoint modal logic designed for reasoning on finite trees, along with a satisfiability-testing algorithm that performs well in practice. The fully implemented system allows to effectively solve a whole class of problems involving XPath queries, regular tree types and any boolean combination of them (like query containment, and query satisfiability in the presence of schemas).
