For the past few days I’ve been at the “Knowledge Organization and Data Modeling in the Humanities” workshop in Rhode Island. It’s been a treat to participate in a conversation about some of the most ancient and enduring questions we have as human beings: How do we model the world? How do we model models of the world? And how—and now we’re approaching the Borges parable “Exactitude in Science”—do we model our modeling of our models? This is all in the context of the digital humanities, of course, and therefore packaged up and explicated through xml and questions about ontological structures (both in terms of Aristotle and data schemata), but the conversation should be of interest to anyone interested in how it is we know what we know.
