The Information Flow Framework (IFF) [1] is a descriptive category metatheory currently under development, which is being offered as the structural aspect of the Standard Upper Ontology (SUO). The architecture of the IFF is composed of metalevels, namespaces and meta-ontologies. The main application of the IFF is institutional: the notion of institutions and their morphisms are being axiomatized in the upper metalevels of the IFF, and the lower metalevel of the IFF has axiomatized various institutions in which semantic integration has a natural expression as the colimit of theories. Some of the ideas used in this paper first appeared in papers by Joseph Goguen [2] and the author [3], and discussions on the SUO email list. See also the companion paper [4]. Keywords: descriptive category metatheory, institutions, semantic integration "Philosophy cannot become scientifically healthy without an immense technical vocabulary. We can hardly imagine our great-grandsons turning over the leaves of this dictionary without amusement over the paucity of words with which their grandsires attempted to handle metaphysics and logic. Long before that day, it will have become indispensably requisite, too, that each of these terms should be confinedto a single meaning which, however broad, must be free from all vagueness. This will involve a revolution in terminology; for in its present condition a philosophical thought of any precision can seldom be expressed without lengthy explanations."

Creativity is sometimes taken to be an inexplicable aspect of human activity. By summarizing a considerable body of literature on creativity, I hope to show how to turn some of the best ideas about creativity into programs that are demonstrably more creative than any we have seen to date. I believe the key to building more creative programs is to give them the ability to reflect on and modify their own frameworks and criteria. That is, I believe that the key to creativity is at the metalevel. In the AAAI-1998 Presidential Address, for example, David Waltz said that creativity is a key topic for AI research because it is an essential element of human intelligence (Waltz 1999).

The Seventeenth American Association of Artificial Intelligence (AAAI) and the Twelfth Innovative Applications of Artificial Intelligence (IAAI) conferences were jointly held in Austin, Texas, on 30 July through 3 August. They continue to provide a growing wealth of research stretching into many of the areas of AI. Coupled with demonstrations of the emerging and deployed IAAI techniques, the joint conference results in a complete survey of breaking technology. With the decade's events in highperformance desktops and "invisible" computing, AI has flourished and now expands from its classical cognitive architecture roots into intense gaming and wireless devices. AI successfully reaches these areas with its continuing multidisciplinary collaborations and creativity.
