HELIO, the Heliophysics Integrated Observatory, was a three year EU funded project and started in June 2009.

The Heliophysics Integrated Observatory, HELIO, will deploy a distributed network of services that will address the needs of a broad community of researchers in heliophysics. HELIO will provide the most comprehensive integrated information system in this domain; it will coordinate access to the resources needed by the community, and will provide access to services to mine and analyze the data.

The project partners included institutions from France, ireland, Italy, Switzerland, the UK and the USA.

The project used Taverna as the mechanism for running its workflows.
