The IAI-DIS is a collaborative database system through which scientific organizations in the Americas can contribute and share information about their Global Change data holdings. It was designed as a network of national nodes, interconnected by the Internet, offering anyone with a Web browser, free distributed search capability at both directory and inventory ... levels. Participating organizations in each country can remotely submit and update metadata about their assets, also at no charge.
The DIS is coordinated by the IAI as a tool to foster and support international scientific cooperation and joint research efforts in the area of Global Change. The first IAI-DIS was installed at the IAI Directorate in Brazil and began providing service in November, 1999. The Uruguay node was installed in August, 2000 and the other countries will implement their national nodes shortly thereafter. The IAI hopes to have all member countries joining this effort in the near future.
This dataset makes reference to the presentation used by Luis Marcelo Achite, IAI-DIS Manager, where he presented general information about the IAI-DIS system, its concepts, some technical details, and the architecture of the system.
Some background information about the IAI (main objectives) was presented as well. Here is the list of presented itens: 1) The FGDC/CSDGM Standard used by IAI-DIS; 2) The Z39.50 protocol used to search and retrieve information; 3) Metadata Clearinghouse and 4) IAI-DIS System.
