"These ambiguities, redundancies and deficiencies remind us of those which doctor Franz Kuhn attributes to a certain Chinese encyclopaedia entitled 'Celestial Empire of benevolent Knowledge'. In its remote pages it is written that the animals are divided into: (a) belonging to the emperor, (b) embalmed, (c) tame, (d) sucking pigs, (e) sirens, (f) fabulous, (g) stray dogs, (h) included in the present classification, (i) frenzied, (j) innumerable, (k) drawn with a very fine camelhair brush, (l) et cetera, (m) having just broken the water pitcher, (n) that from a long way off look like flies." — Jorge Luis Borges, The Analytical Language of John Wilkins


Liber is a resource cataloging application. It can be used to catalog any resource identifiable by a URI, meaning it can be used to catalog anything, however it is typically used to catalog web-based resources. Liber has two interfaces, one for those creating the catalog, and one for those using it. Currently, the interface for catalog creators is simplistic and limited in functionality. The interface for users, however, is more complete, featuring a "web portal" style interface intended to make it easy for users to quickly find very specific subsets of cataloged resources. See for an example of an active Liber portal.

Liber is implemented in the Ruby programming language. The cataloging information, or metadata, is stored as RDF/XML.
