Data dictionaries

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

1. CDI Parameter Groups were specified using four-byte codes that refer to Parameter Groups in the BODC Parameter Dictionary.
2. BODC parameter codes
3. SEA-SEARCH Disciplines were used as the top layer in the CDI interface parameter discovery hierarchy
   • B Biology
   • C Chemistry
   • D Physics
   • G Geology
   • M Atmosphere
   • O Cross-discipline
   • Z Administration and dimensions
4. SEA-SEARCH Agreed Parameter Groups (APGs) were used as the second layer in the CDI interface parameter discovery hierarchy.
5. CDI Platform Codes
6. 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.
