摘要

Information portals are means for the delivery of information services to interested groups. The complexity of the agri-food sectors requires a differentiated infrastruc-ture of information portals which serves different categories of information interests. Enterprises information needs build on enterprise-specific information and on information with interest for groups of enterprises which are on the same stage of the food production process or which cooperate within a vertical produc-tion chain. The paper discusses various information delivery alternatives and out-lines models for the design of an information delivery infrastructure for sectors of the agri-food production chain.
