Embrapa Information Agency

The Embrapa Information Agency is a web system that makes it possible to organize, store, publicize, and access technological information and knowledge generated at Embrapa and other research institutions. The information is organized hierarchically in a tree structure called the Tree of Knowledge.
The Embrapa Information Agency contains all of the Trees of Knowledge developed by Embrapa’s decentralized units pertaining to agribusiness products and themes. The first three levels of the hierarchy contain generic knowledge, while the deeper levels present more specific knowledge. Each item in the Tree of Knowledge is called a node, which is defined at each successive subdivision (sub-node) of the contents. The Tree of Knowledge contains validated information about all stages of the production chain (e.g. plant cultivation and animal raising) and the most diverse themes. The information can be accessed by navigating a hyperbolic tree, navigation over hypertext, or the use of a search service: Browsing of the hyperbolic tree makes it possible to visualize the ramifications and sub-nodes of each basic node. Browsing over hypertext shows nodal and sub-nodal contents and enables access to the document file. The search service makes it possible to identify the route followed to reach the information in the hyperbolic tree when the user types in the subject desired in the search box. The advanced search option permits quality and precision retrieval of the information requested.
