A portal named MISAWIsta (Meteorological Information System)was created which allows users to search for primary data and relatedpublications found in Pangaea and Fedora information systems respectively.The user has the possibility (in case of measurement data) toview the results and download them as CSV- or MarineXML-file.Given that Pangaea and Fedora information systems have been implementedas a Web Service, a PHP-based SOAP-Client was writtento expose these data. The SOAP-Client prepares the query results andpresents them to the user. This work describes the conception anddevelopment of the prototype.
