The intrusion of the Internet drastically modified the historical cycles of communication between authors, providers and users. Today, information is often the result of the interaction between data and the knowledge based on their comprehension, interpretation and prediction. Nowadays important goals involve the exchange of heterogeneous information, as many real life and even specific scientific and technological problems are all interdisciplinary by nature. For a specific project, this signifies extracting information, data and even knowledge from many different sources that must be addressed by interoperable programs. Another important challenge is that of corporations collaborating with each other and forming coalitions and partnerships. One development towards achieving this challenge is organizational hubs. This concept is new and still evolving. Much like an airport hub serving air traffic needs, organizational hubs are central platforms that provide information and collaboration specific to a group of users' needs. Now companies are creating hubs particular to certain types of industries. The users of hubs are seen as communities for which all related information is directly available without further searching efforts and often with value-added services.
