Despite the availability of several data integration tools, the proliferation of biological databases and resources over the Internet is still challenging the bioinformatics community. Whereas current research is targeted towards the use of ontologies and P2P architectures, most of the Web data still remain accessible through rudimentary interfaces like query forms, that grant access to the underlying data management system. In this paper, we present a formalism based on feature logics used for representing and comparing those resources. The purpose of our work is twofold, and concerns reasoning on traditional query forms capabilities for creating join paths through resources, and the use of the generated paths as a support for cascading joins across heterogeneous and distributed datasets.
