The UniCats Project

trader research


The success of the internet has made some dramatic changes in the way of supplying scientists and students with scientific literature. It has started to change into an information market, where the value of a piece of information is determined by the law of supply and demand. Libraries, publishing houses, technical report servers, document delivery services and the bookstore around the corner offer their services in the WWW. The customer in this market is unable to find providers delivering the desired piece of indormation under his/her conditions for a fair price. The UniCats trader offers a solution for this problem in the open, distributed and heterogeneous environment of the information market.
