  2. Overview • Introduction • Study Objectives • Project Team • Initial tasks • Use Cases • Design • Approach • Architecture • Possible data and model nodes • Schedule & Perpectives ViSpaNeT

  3. Study Objectives • Provide user-tailored centralized access to distributed: • real-time and historical space environment data • outputs from numerical models of the space environment • provide a system for chaining these data and models • Develop a distributed system demonstrator, allowing coupling of these products in order to provide warnings of a sub-set of space weather hazards for space systems • Develop a prototype environment (ViSpaNeT) with focus on technology demonstration for space weather service provision • Develop a policy/approach for distributed processing in line with the concept of a virtual observatory ViSpaNeT

  4. Study Team ViSpaNeT

  5. Initial project tasks • User survey performed including a number of “Premium users” • The results synthesised into user requirements • Review of existing data and models • Review of VO Technologies • User Requirements where traced to possible data and model nodes • Identify data and model workflows ViSpaNeT

  6. Overall description • VisPaNeT has three main functions : • Run models remotely on request with data chosen by the user • Run workflows providing alerts • Search and get space weather data from remote servers • 26 use cases established describing user interaction • User input parameters • Data input from external nodes • Model workflow ViSpaNeT

  7. UC 12 -- Forecast of geomagnetic storms

  8. Use Case List ViSpaNeT

  9. Vispanet Architecture • A Central Node provides • The user interface • User administration • Data Registry (SPASE Compliant) • Model Registry • Automated runs for alert generation • Remote Nodes must provide a standardised interface for connection with the central node • Interface according to VO Tables • Description for data registry compatible with SPASE • Description for model registry ViSpaNeT

  10. Overview of ViSpaNeT Nodes ViSpaNeT

  11. Overall Architecture VOTable SPASE Detailed description of every model ViSpaNeT

  12. VisPaNet is designed according to VO standards • VisPaNeT architecture is distributed • Designed according to SOA (Service Oriented Architecture) • Data and models nodes must provide SOAP Web services to access their data and execute their models • Providers (nodes) must provide a description of their assets • Description must be compatible with the SPASE Model for data. • Stored in a Central Registry (Central Node) • The Central Node exchange data with remote nodes in VOTable format ViSpaNeT

  13. SPASE & VOTable • SPASE: Space Physics Archive Search and Extract • It is a model to describe solar and space physics data • In ViSpaNet, SPASE is used to provide semantic interoperability in the distributed system • It was originally created by the Heliophysics scientific community • VOTable is a format for tabular data • International Virtual Observatory Alliance (IVOA) standard • Results from data and model nodes will be exchanged using this format ViSpaNeT

  14. Outlook & Perspectives • PDR/CDR concluded in early November 2010 • Agreed on use cases to be implemented • Presented architecture design • Discussed node interfaces • Next Phase: Implementation • Establish model ICDs • Implement central node • Implement Node interfaces ViSpaNeT

  15. Summary • ViSpaNeT will provide a demonstrator for a distributed system for accessing data and models • Use cases were established detailing model and data interaction • The approach will follow Virtual observatory paradigm using SPASE ontology and VOTable interfaces • A central node provides the user interface and connects remotely distributed data and models • Standardised interface specifications allows flexibility for exchanging information between nodes • The systems provides flexibility in exchanging data or model providers, concentrating on the functionality • Design has been completed and a prototype will be implemented in the course of 2011 ViSpaNeT
