Library::* : a toolkit for digital libraries

In last years the amount of digital documents has increased dramatically. Unfortunately the same did not occur with the structure and organization of the information. Traditionally we built a digital library using a catalog with documents' meta-information including a conceptual classification and an ontology of concepts. In this document we present a set of modules to help in the task of building and maintaining a digital library. It includes a module to work with ontologies, a set of modules to handle specific catalog formats (like BibTeX), a module to define new catalog formats and a tool to integrate ontologies and multi-format catalogs in a web browse-able knowledge-base
