To facilitate access to all data and information related to scientific ocean drilling, theIntegrated Ocean Drilling Program (IODP) is developing a web based informationservice (Scientific Earth Drilling Information Service, SEDIS). The three main datacontributors to SEDIS currently are the IODP implementing organizations (IOs) fromthe United States (USIO), Japan (CDEX) and Europe with Canada (ESO). SEDISintegrates the data search of the IO databases by harvesting distributed metadatawithout the necessity to centralize the data storage.Presently SEDIS provides the metadata for data discovery and harvesting as suppliedby the IOs (http://sedis.iodp.org). The access to publications, reports, minutes,citations and post expedition research is also implemented and the content of thedatabase is continuously increasing. An expedition catalog completes the database.The next phase in developing SEDIS will include an advanced data search andvisualization and mapping tools.In the future SEDIS will also be able to include other available scientific drilling datafrom continental or lake drilling. SEDIS is designed to integrate distributed scientificdata via metadata by using international standards for metadata and data exchange andtransfer and uses open source components.
