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 (Vi. Spa. Ne. T) 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 18 th November 2010 Vi.

Vis. Pa. Net is designed according to VO standards • Vis. Pa. Ne. T 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 18 th November 2010 Vi. Spa. Ne. T 12

SPASE & VOTable • SPASE: Space Physics Archive Search and Extract – It is a model to describe solar and space physics data – In Vi. Spa. Net, 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 18 th November 2010 Vi. Spa. Ne. T 13

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 18 th November 2010 Vi. Spa. Ne. T 14

Summary • Vi. Spa. Ne. T 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 18 th November 2010 Vi.
