Abstract The Geosciences Network (GEON) project has been developing cyberinfrastructure for data sharing in the Earth Science community based on a service-oriented architecture. The layered architecture consists of Core, Middleware, and Applications services. Core services provide system-level functions (e.g. user authentication), Middleware services provide generic capabilities (e.g. catalog search), and Application services provide functions that users directly interact with, including applications that are specific to Earth Sciences. The GEON 'service stack' includes a standardized set of these services and the corresponding software modules. The GEON Portal provides Web-based access to these services via a set of portlets. This service-oriented approach has enabled GEON to expand to new partner sites and leverage GEON services for other projects. To facilitate interoperation in a distributed geoinformatics environment, GEON is focusing on standards for distributed search across federated catalogs.
