The Unidata Seminar Series presents a talk by Dr. Stefano Nativi of the National Research Council of Italy (IIA-CNR, Florence Division). The talk, titled GEOSS Common Infrastructure and the Brokering Framework, will describe progress on using service brokering techniques in a federated multidisciplinary data environment as part of the Global Earth Observation System of Systems.
Nativi provided this abstract for his talk:
Global sustainability research requires an integrated multidisciplinary effort underpinned by a collaborative environment discovering and accessing heterogeneous data across disciplines. Traditionally, interoperability has been achieved by implementing federation of systems. The federating approach entails the adoption of a set of common technologies and standards. This presentation argues that for complex (and uncontrolled) environments (such as global, multidisciplinary, and voluntary-based infrastructures) federated solutions must be completed and enhanced by a brokering approach — making available a set of brokering services. In fact, brokerage services allows a cyber-infrastructure to lower entry barriers (for both data producers and users) and to better address the different domain specificities.
The brokering interoperability approach was successfully applied and enhanced by the GEOSS (Global Earth Observation System of Systems) Initiative. The GEOSS Common Infrastructure (GCI) adopts a powerful brokering framework called GEO DAB (Discovery and Access Broker). GEO DAB provides a services platform to discover, evaluate, access, transform, and portrayal geospatial datasets. GCI and the GEO DAB address most of the Bi Data challenges affecting GEOSS. The seminar introduces the GCI with particular attention to the DAB role and the next coming research and development topics.
Nativi will present his seminar in room 1001 (the small auditorium) at UCAR Foothills Lab 2, on Thursday, July 10th at 4:00 pm. The seminar will be webcast live at this URL.
