Verdi: An Automated Tool for Web Sites Verification

Verdi is a system for the automated verification of Web sites which can be used to specify integrity conditions for a given Web site, and then automatically check whether these conditions are actually fulfilled. It provides a rule-based, formal specification language which allows us to define syntactic/semantic properties of the Web site as well as a verification facility which computes the requirements not fulfilled by the Web site, and helps to repair the errors by finding out incomplete/missing Web pages.
