World Information Architecture Day, March 4, 2023















There are two approaches to the problem of integrating information, and both are important. The “top-down” approach emphasizes modeling uniformity and modeling power; it generally means defining models and persuading providers of information to understand them, and to make the information they provide conform to them. The bottom-up approach emphasizes modeling diversity and minimality; the idea is to take whatever information is available, and, with or without the provider’s cooperation, to try to make one or more kinds of sense out of it. Each kind of sense is reflected in an ad-hoc model that captures only as much of the internal consistency of the incoming information as was needed for the sense that needed to be made. Our presentation will focus on the bottom-up approach, with the purpose of showing that it offers vital benefits, and that it is feasible, robust, exportable, maintainable and interchangeable.    (2IP5)
