The goal of this research contract has been to create Greenstone, a leading-edge, fully-internationalized digital library system, and ensure that it is widely perceived as a leading content management system for digital libraries. The system is issued under an open source software licence. The project received the 2004 IFIP Namur award for “contributions to the awareness of social implications of information technology, and the need for an holistic approach in the use of information technology that takes account of social implications,” and was a finalist for the 2006 Stockholm Challenge.The chief measure of success is international adoption. The Greenstone software is currently downloaded 5000 times/month, of which 60% are documentation downloads and 40% are software downloads. It is not known how many of these downloads translate into running systems. However, our web site points to examples of public collections hosted in (or whose material is focused on) Argentina, Australia, Canada, China, East Timor, Germany, Greece, India, Italy, Kyrgyzstan, Namibia, Netherlands, Pakistan, Philippines, Russia, Rwanda, Slovenia, Sudan, USA, UK, and Vietnam. The user interface has been translated into 38 of the world’s languages. Seventy countries are represented on the project mailing list.UNESCO’s Information Society Division promotes Greenstone under its “Information for All” programme. Both the UN Food and Agriculture Organization and UNESCO Institute for Information Technology in Education have produced comprehensive training materials on the use of the software. Training is a key bottleneck in the adoption of advanced digital library technology, and our project staff have run courses—some sponsored by UNESCO and others locally sponsored—in Austria, Canada, Cuba, Fiji, India, Italy, South Africa, Tanzania, Thailand, UK and USA. Other people have mounted courses in Botswana, Kazakhstan, Senegal and Vietnam. Greenstone is used for teaching at the University of Illinois, the top-ranked US library school, and other institutions including the University of Texas, University of Iowa, Drexel University, University of Kentucky, University of Alberta, University of Surrey, Nanyang Technological University and the National University of Singapore.The Greenstone digital library software has won this striking degree of international recognition because it offers facilities that go well beyond other digital library solutions. In particular, its flexible and extensible architecture accommodates all commonly-used text and metadata formats, from Word and PDF documents through PowerPoint and Excel to conventional library records. It is based on a broad and detailed abstraction of the activities undertaken by digital librarians, which is built into a unique software component called the Greenstone Librarian Interface. Our concept of document and metadata interoperability, implemented in the software, embraces many international standards. We have developed a novel approach to the generation and maintenance of multilingual user interfaces that keeps track of the status of each translation and allows it to be updated over the web by the end user community. Finally, Greenstone incorporates striking advances in appropriate technology for developing countries, including a small footprint, web archiving, and a search facility that runs on technology ranging from Windows 3.1 to the iPod.Open source software that is widely adopted internationally provides an excellent opportunity for the development of commercial support and consulting services. A company set up in Hamilton to provide consulting and web hosting activities related to Greenstone has undertaken several international contracts, and (in partnership with our project) has won a major contract from the National Library. DL Consulting is among New Zealand's fastest-growing companies, appearing in the latest Deloitte/Unlimited Fast 50 Index. The Hauraki Iwi is using Greenstone for the Hauraki Digital Library, which contains collections of bilingual stories, video/audio of oral history, and photographs; this is intended as a model for other Iwi.
