The SEA-SEARCH Common Data Index (CDI) was a pilot system providing users a public internet tool to search and obtain up-to-date information about marine data currently held in individual partners' databases. The following dictionaries were an integral part of the system
- CDI Parameter Groups were specified using four-byte codes that refer to Parameter Groups in the BODC Parameter Dictionary.
- BODC parameter codes
- SEA-SEARCH Disciplines were used as the top layer in the CDI interface parameter
- B Biology
- C Chemistry
- D Physics
- G Geology
- M Atmosphere
- O Cross-discipline
- Z Administration and dimensions
- SEA-SEARCH Agreed Parameter Groups (APGs) were used as the second layer in the CDI interface parameter discovery hierarchy.
- CDI Platform Codes
- CDI Instrument Codes
The SEA-SEARCH project ended in 2005. The CDI and the above dictionaires are now being used and developed further by the EU SeaDataNet project.
