The paper discusses the issue of views in the Web context. We introduce a set of languages for managing and restructuring data coming from the World Wide Web. We present a spe- cific data model, called the ARANEUS Data Model, inspired to the structures typically present in Web sites. The model allows us to describe the scheme of a Web hypertext, in the spirit of databases. Based on the data model, we develop two languages to support a sophisticate view definition process: the first, called ULIXES, is used to build database views of the Web, which can then be analyzed and integrated using database techniques; the sec- ond, called PENELOPE, allows the definition of derived Web hypertexts from relational views. This can be used to generate hypertextual views over the Web.

Abstract

The paper discusses the issue of views in the Web context. We introduce a set of languages for managing and restructuring data coming from the World Wide Web. We present a spe- cific data model, called the ARANEUS Data Model, inspired to the structures typically present in Web sites. The model allows us to describe the scheme of a Web hypertext, in the spirit of databases. Based on the data model, we develop two languages to support a sophisticate view definition process: the first, called ULIXES, is used to build database views of the Web, which can then be analyzed and integrated using database techniques; the sec- ond, called PENELOPE, allows the definition of derived Web hypertexts from relational views. This can be used to generate hypertextual views over the Web.
