A Modal Perspective on Path Constraints

N. Alechina
2003 Journal of Logic and Computation  
Several classes of path constraints for semistructured data are analysed and a number of decidability and complexity results proved for such constraints. While some of these decidability results were known before, it is believed that the improved complexity bounds are new. Proofs are based on techniques from modal logic and automata theory. This modal logic perspective sheds additional light on the reasons for previously known decidability and complexity results.
