摘要：This paper elaborates on initiatives and experiences at the European Space Agency establishment in Frascati (Italy) in implementing a distributed Earth Science data infrastructure. Of particular interest are experiences in the ESA-lead projects GENESI-DR and GENESI-DEC (short for Ground European Network for Earth Science Interoperations –Digital Repositories / Digital Earth Communities), the first one having established a data infrastructure providing transparent access to a network of (mainly European) Digital Repositories, the second one aiming at extending it to a worldwide e-Infrastructure serving heterogeneous communities interested in Planet Earth data, services and applications. Furthermore, potential contributions to the Global Earth Observation System of Systems that would enlarge the world-wide GEOSS Common Infrastructure’s capabilities are described, in response to data producers and consumers expressed needs regarding re-use and dissemination of Earth Observation data across different regions in the world. GENESI-DEC has been recently integrated in the GEO Portal to demonstrate how it can contribute to the enhancement of the GEOSS Common Infrastructure with new data access and processing capabilities. GENESI-DEC is proactive in several OpenGeoSpatial Consortium (OGC) working groups on the following topics: Catalogue Services for the Web, Web Processing Service, Ordering Services for Earth Observation Products Standard, OpenSearch GeoSpatial Standard, Publish/Subscribe Standard, Web Map Context Implementation.
