The NetarchiveSuite software is developed and maintained by The Royal Danish Library (previously two separate institutions - The Royal Library Copenhagen and the State and University Library Aarhus) together with the National Library of France (BnF) and the National Library of Austria (ONB). The National Library of Spain (BNE) and National Library of Sweden (KB-SE) are also active members of the development project.
The NetarchiveSuite is a complete web archiving software package, developed from 2004 and onwards, and used in production to harvest the Danish web since 2005. The primary function of the NetarchiveSuite is to plan, schedule and run web harvests of parts of the Internet. It scales to a wide range of tasks, from small, thematic harvests (e.g. related to special events, or special domains) to harvesting and archiving the content of an entire national domain. The software has built-in bit preservation functionality. The systems architecture allows for the software to be distributed among several machines, possibly on more than one geographical location. The NetarchiveSuite is built around the Heritrix web crawler, which it uses to harvest the web.
