The core idea of Debtags is to use Faceted Categorization for our packages. Faceted Categorization is a 50-years-old library science technique which is being rediscovered by Information Architecture with very good results. The Debtags effort is developing a powerful and flexible system to attach "tags" to packages, which allow us to explicit some of their attributes, making them available to automated tools such as package managers and web interfaces.
