Welcome to the IAI-DIS Portal!

The DIS is an Internet-based data and information system with the following objectives in focus: 1) Dissemination of data created within the IAI scientific projects by using a metadata creation and management process; 2) Data discovery; and 3) Contribute for the standardization and exchange of scientific data between investigators and institutions.

The mechanisms that proportionate the fulfillment of these objectives are the DIS Metadata Editor, the DIS Search Process and the DIS Harvest Process. The combination of these 3 mechanisms creates an efficient and reliable system that allows investigators to document data and specially enable free and open access to data.

The DIS Metadata Editor allows the creation, edition, standardization and maintenance of metadata. It is an user-friendly web-based application, where no other extra tool is required than a standard web browser. Each metadata created with this tool is based on well-known scientific standards and can be organized in accordance with the NASA´s Global Change Master Directory Science Keywords.

The DIS Search Process, through the Search Tool, facilitates the identification of articles, presentations, posters and other information produced by the IAI Investigators. Visitors can use different set of search criteria to look for metadata and consequently any data. The search process is intuitive and similar to other search and retrieve applications and search portals, like Google.

The DIS Harvest Process is an internal process, but not least important. It collects metadata that are marked as "searchable" by the Investigator and create or update the index. The "harvest" process is done once a day, so every metadata modification is sent to the index as part of the daily process, which keep the metadata list up-to-date, and consequently the data list.
