Code and format definitions

Codes can make life easier ©

BODC handles a wide range of marine data sets collected and provided by numerous organisations from the UK and around the world. Data standardisation, both for parameters and file format, is essential for their professional management. Details of our methods of standardisation both present and historical are provided here.

Standardised parameters

All data in our National Oceanographic Database (NODB) or the project database maintained by BODC are held in our standard units and are assigned parameter codes as described in the BODC Parameter Dictionary.

Standardised file formats

BODC distributes data in various standard formats

• BODC request (ASCII) format
  A BODC output format designed to handle most types of data held by BODC.
• Ocean Data View (ODV) format
  A BODC (SeaDataNet) ODV format designed to handle most types of data held by BODC.
• QXF (a netCDF) format
  QXF is a BODC defined subset of the binary format netCDF.
• AXF format
  BODC no longer distributes data in AXF format — AXF details are provided for historical files

Vocabulary content governance

Initiatives such as SeaDataNet and MarineXML are working toward the International Organization for Standardization (ISO) 19115 standard. They are using code lists and controlled vocabularies to regulate the population of metadata.

Vocabulary content governance is very important in order to stay up-to-date and in sync with ongoing developments. Therefore, a combined SeaDataNet and MarineXML Vocabulary Content Governance Group (SeaVoX) has been set up.
