Abstract

Quo is a framework for the development of applications that use WWW data. Quo models the WWW accessible data using a dynamic semistructured data model called Quom (Quasi-Object Model). Within a semistructured model, Quom introduces (I) Object-Oriented features, (2) a structure declaration which is a “lightweight” schema definition. On the other hand, Quom relaxes the requirement, of Object-Oriented data models, of a strict schema definition. This enables dealing with the irregularities of WWW extracted data and with self-describing data formats “a la” XML. Data extraction rules are defined using Quodl, the Quasi-Object Definition Language. Quodl data extraction rules use XSL to analyze and extract HTML/XML data and regular expressions are used for the analysis of and extraction from, raw data
