Overall Architecture 18th November ViSpaNeT SPASE VOTable 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 18th November 2010ViSpaNeT12

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 18th November 2010ViSpaNeT13

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 18th November ViSpaNeT

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 th November ViSpaNeT

SPASE DATA MODEL The SPASE Data Model provides enough detail to allow a scientist to understand the content of Data Products (e.g. a set of files for 3 second resolution Geotail vector magnetic field data for 1995 to 2002) together with essential retrieval and contact information. A key resource type in the SPASE model is Numerical Data which consists of a set of files containing sequential values of one or more physical variables, which often have internal vector and/or spectral structure. Numerical Data are often presented in images( gif or jpeg) and are refered to as Display Data. Catalogs are lists of events. Granule describes individual files within Catalogs, Numerical or Display data. 18th November ViSpaNeT
