Cosma / Communication / Knowledge / Realm (Zoom!)

Collecting hundreds of thousands of Knowledge Resources over the course of decades is easier than you might think. Figuring out how to organize them in order to make them findable is hard. Adding the additional constraint of needing to organize them into a literal map in order to create 3D interfaces to enable spatial Knowledge Navigation creates a sticky problem. Of course, there is a long history of how to deal with such Knowledge Organization problems. However, there is no perfect solution — there are only a series of trade-offs in adopting any ontology. In practice, Cosma does not use any specific existing system to “layout” knowledge such as the Great Chain of Being or the Tree of Diderot and d’Alembert. Instead, all of the virtual spaces that serve as 3D interfaces to Cosma are laid out into five “Realms” based upon an amalgamation of taxonomies for organizing reality into hierarchies and physical maps. 1

1.   The problem of how to organize and present the systematic, top down inventory of Knowledge Resources was such a sticky problem, Hopper ended up taking graduate courses in Cataloging, Reference and Digital Libraries at Simmons University’s School of Library and Information Science to figure it out. The review of all of the text based and cartographic layouts that were considered, and how the chosen ones were integrated into the final layouts used for Cosma‘s Content Outline and 3D Interfaces is a long story — it’s way too long to tell in this little footnote 🙂
