Objetivo The ESGO will create a virtual archive by federating solar data centres scattered across Europe into a data Grid. This will dramatically enhance access to data for both the solar and non-solar communities and will for the first time make data available on demand to the user. The project will employ intuitive web-like interfaces and advanced search and visualization tools to match observations made by numerous space- and ground-based observatories. A major innovation will be the provision of a Solar Feature Catalogue that will allow complex searches based on solar phenomena and events. The EGSO will also provide the facility for the evaluation of extended time series of large, complex data sets at source, without the need to download them. This Grid test bed will federate six data centres located in France, Italy and the United Kingdom, but the design of the EGSO will scale to include as many data archives world-wide as wish to participate.Objectives:The ESGO aims create a virtual archive by federating solar data centres scattered across Europe into a grid in order to enhance access for both the solar and non-solar communities. EGSO will create a catalogue of solar features at different wavelengths to provide an innovative way of conducting data searches based on phenomena. It will create a unified catalogue of space- and ground-based solar observations to facilitate the identification of matching data sets based on date, time and location on the Sun, and provide search and visualisation tools using web-based interfaces to assist the user when examining the catalogues. Other tools will locate data identified in the search and retrieve them for more detailed analysis, extracting and calibrating them where necessary. EGSO will also provide the facility for users to upload their own software to analyse extended time intervals of large, complex data at source data centres, where their volume makes it impractical to retrieve them.Work description:The EGSO will be constructed from several component parts, catalogues, search and visualisation tools, and federation middleware that combine many solar data centres into a virtual archive. The observational catalogues will be built from existing catalogues where possible, but will use a standard format designed to facilitate searching for matching observations at many wavelengths. Dependencies on ancillary data will be removed to produce catalogue files that are independent and self-describing; if required, observatories will be consulted to help resolve inadequacies in existing logs. The solar feature catalogue will be created using image recognition tools developed for the project. Full disk ground- and space-based imagery will be processed to build a catalogue of the occurrence and location of features such as filaments, active regions, flares, coronal holes. Tools to search the catalogues using web-based user interfaces will be developed with visualisation techniques designed to aid the user in their selections of the data; full-disk synoptic images and quick-look products will be used to assist the process. The federation middleware provides the underlying fabric of the EGSO. It must provide controlled access to selected data and other resources at the sites, while ensuring the security of the grid as a whole. While standard data reduction techniques based on Solar Soft will be used for the extraction and calibration of data, the capability will be created to execute code provided by the user for more complex analysis of large volumes of data at the data source. Where possible, tools used in the project will be based on open source code - these will be augmented and refined as necessary and any such additions will also be open source. Extensive consultations with users will ensure EGSO provides the capabilities the community requires. Issues related to user authentication and security for the diverse user community will be resolved during the project.Milestones:1) Architectural design of the EGSO based on scientific requirements, user community input, and surveys of appropriate technologies;2) Demonstration federation of solar data centres, providing limited data access and a test bed for full development;3) Creation of observing catalogues and the catalogue of solar features;4) Full federation of data centres, with tools for integrated data extraction, processing and retrieval through interactive catalogue searches, providing full user access.
