I know there is research out there on database integration, creating a "monolithic" global interface in which queries are expressed in a universal language; however, that's not what I'm after. Rather, I'm seeking references to research along the lines of what's been called the "federated" approach, in which no global schema is created in advance. Since responses may not be of general interest, can I suggest e-mailing responses to me at resnik@grad1.cis.upenn.edu? I'll post a summary of the responses I receive. Thanks!
