Despite the popularity of the World Wide Web as a development platform, a proper description of its architectural principles and design criteria has been achieved only recently, by the introduction of the Representational State Transfer (REST) architectural style which defines the <em>resource</em> as the key abstraction of information.
In fact, languages and tools currently used for Web programming generally suffer from a lack of proper understanding of its architecture and design constraints, and from an abstraction mismatch that makes it hard to exploit the Web potential.

Declarative languages are well-suited for a programming system aimed at being respectful of the Web architecture and principles.
Among logic technologies, tuProlog has been explicitly designed to be one of the enabling components of Internet-based infrastructures: its engineering properties make it suitable for use on the Web, where logic programming allows modification of resource behaviour at runtime.
Accordingly, in this paper we present a Prolog-based logic model for programming Web resources, and outline a framework for developing Web applications grounded on that model.
