Description:Heliophysics Integrated Observatory
Abstract:Heliophysics is a new research field that explores the Sun-Solar System Connection; it requires the joint exploitation of solar, heliospheric, magnetospheric and ionospheric observations. HELIO is designed around a Service-oriented Architecture. The initial infrastructure includes services based on metadata and data servers deployed by the European Grid of Solar Observations (EGSO). We will extend these to address observations from all the disciplines of heliophysics; differences in the way the domains describe and handle the data will be resolved using semantic-mapping techniques based on an ontology built from data models that exist in the domains. Processing and storage services will allow the user to explore the data and create the products that meet stringent standards of interoperability. These capabilities are orchestrated with the data and metadata services using the Taverna workflow tool. HELIO will be a key component of a worldwide effort to integrate heliophysics data and will coordinate closely with international organizations to exploit synergies with complementary domains.
