URIs are the lingua franca of the web. They are in every web page and every HTTP request. In a practical sense, they represent the realization of the web. Without them, the web would cease to exist. The situation is very different in the world of the RDBMS. Here, URIs are interlopers. Some RDBMS have provided basic support for URIs via their object extension facilities; however, URIs are still not considered a formal part of RDBMS schema design. This talk explores how URI could evolve to become as important to RDBMS Schemas as it is to the web. One aspect of URI 'types' this presentation will cover is the use of Web Application Description Language (WADL). WADL has been described as SQL Schema meets REST. WADL is metadata describes the functional and structural aspects of a URI 'type' that a web site or other provider offers through HTTP.
