4. Conclusions / Future plans
The described system is currently under development and could thus not prove its feasibility yet. It is developed in collaboration with the C3Grid project and is set up to offer each current and potential data provider the opportunity to expand the system to include specific requirements needed for their data by means of stylesheets or XML templates. Once the system is in place, it might prove useful to establish a direct connection between the eXist database and the C3Grid portal.
3. Impact
The interfaces of the presented system offer a convenient way to explore and use the XML implementation ISO19139 of the ISO19115 format. They thus help to describe existing or emerging data in order to share them. The ISO19115 format has proven useful to describe GIS and earth system science data and is already in use by several academic and business actors (e.g. ANZLIC, ESRI, con terra GmbH). The German C3Grid (part of the D-Grid initiative), adapted this format for the grid field to offer a common view and access to data of the large German climate and earth system data providers. This C3Grid framework is set up to be expandable by further data providers. The EGEE infrastructure e.g. has been integrated as both, a data provider and processor. The presented system is intended to attract further EGEE users or earth system science data providers to share their data via this framework with the traditional earth system science community.
1. Short overview
A precondition to effectively share and exchange data is a proper description of its content, properties and quality in a standardized metadata format. Yet, a metadata format, complex enough to describe diverse data for a broad community, needs tools to comfortably view, create, parse and update these metadata automatically as well as manually. We develop a system of such tools, based on XML standards, for metadata in the ISO19115/19139 format, describing earth system science data.
