摘要：E-science on the Web plays an important role and offers the most advanced technology for the integration of data systems.It also makes available data for the research of more and more complex aspects of the system earth and beyond.The great number of e-science projects founded by the European Union (EU), university-driven Japanese efforts in the field of data services and institutional anchored developments for the enhancement of a sustainable data management in Germany are proof of the relevance and acceptance of e-science or cyberspace-based applications as a significant tool for successful scientific work.The collaboration activities related to near-earth space science data systems and first results in the field of information science between the EU-funded project ESPAS, the Japanese IUGONET project and the GFZ ISDC-based research and development activities are the focus of this paper.The main objective of the collaboration is the use of a Semantic Web approach for the mashup of the project related and so far inoperable data systems.Both the development and use of mapped and/or merged geo and space science controlled vocabularies and the connection of entities in ontology-based domain data model are addressed.The developed controlled vocabularies for the description of geo and space science data and related context information as well as the domain ontologies itself with their domain and cross-domain relationships will be published in Linked Open Data. Semantic Web based mashup of the earth and space science related Japanese IUGONET, European Union ESPAS and GFZ ISDC data systems and services.
