Comparative modeling of Vickery's faceted classification and the œuvre of S. R. Ranganathan...

 In an effort to make sense of both Ranganathan’s work and Vickery’s we modeled the
process involved in classification using the IDEF0 (Integrated Definition for Function
Modeling) formalism. This allows us to see five distinct parts of the classification process:
actions, inputs, outputs, mechanisms, and constraints.
