A Logical Model for Metadata in Web Bases

In systems that provide integrated management of both structured, database--style, data and semistructured, Web-style, data, metadata may allow for the explicit management of information about the structure and data content of pages. Unfortunately, the HTML standard doesn't offer any explicit framework for document metadata management. The eXtensible Markup Language vice versa allows for the explicit description of the structure of a document, but it lacks of database perspective. The aim of this paper is then to describe an approach to the generation of database--derived Web meta--information that is based on a logical model for Web pages and to show how this approach can be effectively used for both HTML-- and XML--based systems. 1 Introduction The Web scenario is increasingly being populated by sites where data play a major role. These sites are usually built over one or more underlying databases and they are mainly used to dynamically present a hypertext view to the user. However,..
