摘要

The paper describes practical approach to implementation of satellite data archive using Globus Toolkit4 components. The solutions consists in converting a hierarchy of remote data files available via FTP into Gridenabledarchive. All etries of such archive will be indexed using arbitrary but pre-defined XML schema. Theinformation will be exposed via MDS4 Index service and the actual data will be exposed via GridFTP. Theschema used in our solution is simple enough for understanding but in a real life applications we should usemetadata standards such as ISO 19139 and ISO 19115 in particular. A working prototype of the archivedescribed in this paper is deployed on the Grid testbed of Space Research Institute of National Academy ofScience and National Space Agency of Ukraine (SRI-NASU-NSAU). The SRI-NASU-NSAU testbed is brieflydescribed in this paper as well.
