Invenio, the integrated digital library and repository system, is a suite of applications which provides the framework and tools for building and managing an autonomous digital library server. The technology offered by the software covers all aspects of digital library management. It complies with the Open Archives Initiative metadata harvesting protocol (OAI-PMH) and uses MARC 21 as its underlying bibliographic standard. Its flexibility and performance make it a comprehensive solution for the management of document repositories of moderate to large size.
