Digital preservation of CBUC theses with MetaArchive 11th SELL Meeting Porto, June 4th 2011 TDX: repository for Doctoral Theses • Over 10.000 theses • We wanted to do something practical in preservation MetaArchive cooperative: • Bunch of institutions with digital preservation needs • 30 members approx. • most of them in the USA (including the Library of Congress) • just 2 in Europe MetaArchive working model: • Each institution runs a node (cache). • Every cache is a dark archive. • The network of all caches is controlled via the LOCKSS software. • There are 6 copies of each collection spread over the network. • The network continuously checks the integrity of the data. • In case of problem, the system can recover the data. It would be nice to have more partners in Europe. The more we are, the more fun we have. Thanks! CBUC http://www.cbuc.cat TDX http://www.tdx.cat MetaArchive http://metaarchive.org
