Rewriting-Based Navigation of Web Sites: Looking for Models and Logics

In this paper we outline the use of term rewriting techniques for modeling the dynamic behavior of Web sites. We associate rewrite rules to each Web page expressing the Web pages which are immediately reachable from this page. The obtained system permits the application of well-known results from the rewriting theory to analyse interesting properties of the Web site. In particular, we briefly discuss the use of some logics with strong connections with term rewriting as a basis for specifying and verifying dynamic properties of Web sites. We use Maude as a suitable specification language for such rewriting models which also permits to directly explore interesting dynamic properties of Web sites.
