Abstract

Information integration in the World Wide Web has evolved to a new framework where the information is represented and manipulated using a wide range of modeling languages. Current approaches to data integration use wrappers to convert the different modeling languages into a common data model. In this work we use a nested hypergraph based data model (called HDM) as a common data model for integrating different structured or semi-structured data. We present a hypergraph query language (HQL) that allows the integration of the wrapped data sources through the creation of views for mediators, and the querying of the wrapped data sources and the mediator views by the end users.We also show that HQL queries (views) can be constructed from other views and/or source schemas using a set of primitive transformations. Our integration architecture is flexible and allows some (or all) of the views in a mediator to be materialized.
