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 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

Detailed description of every model

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

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

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

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
