GAIA's Reference Model is a generic framework for information brokerage systems. The GAIA Standard describes the GAIA brokerage system in particular and is a specialisation of the GAIA Reference Model. The principal services covered by the GAIA Standard are: discovery of information, goods & services, location of suppliers, negotiation of service level in terms of quality, delivery & price, delivery in the digital domain, authentication, tariffing & payment management. Central to the approach taken by GAIA is the development of generic tools within the GAIA architecture to provide key reusable services, including user access components and mechanisms to use data from existing repositories. The involvement of representative bodies and user communities in trials of the GAIA service is validating the GAIA architecture and contributing to the establishment of business cases for information trading.
