Instrument Name Standards for Marine Data

Contents


Background

In January, 2008, the IOC and JCOMM convened a workshop entitled the IODE/JCOMM Forum on Oceanographic Data Management and Exchange Standards (IOC Workshop Rept. 206), to consider selected principal issues on establishing marine data standards, with the goal of furthering marine data interoperability. In particular the aim of the workshop was to get broad agreement and commitment to adopt a number of standards related to ocean data management and exchange, thereby assembling not only the agreed conditions by which we operate, but in fact enact these agreements in the participants' respective organizations.

Standards Recommendation

Mr. John Graybeal introduced this item and moderated discussions. He reviewed the various lists of institutions that exist. He mentioned that there exist about 14 instrument vocabularies (GCMD, BODC/SDN, NASA, SSDS) but there exist no mappings between these vocabularies. It was noted that there are multiple organizing principles for instruments.

John Graybeal's Summary Presentation

  • British Oceanographic Data Center (BODC)
    • BODC Instruments
    • 2-letter codes
    • Includes UNSPECIFIED
    • The BODC code list put up as a candidate has many faults and is in the process of being replaced by the SeaDataNet L05 vocabulary, partly published but still very much under development and strongly influenced by the MMI devices ontology project
  • Global Change Master Directory
    • GMCD Instruments Key Words
    • Almost completely concerned with satellite sensors
    • 8-letter codes in many cases
    • In other cases, the code is lacking and the full name of the sensor is the code

Decisions

  • The meeting concluded that rather than having multiple lists we should have an instrumentation vocabulary that should be managed by one organization. This organization should be careful about deletion or redefinition of terms (in fact it was recommended not to delete) and new instruments should be added quickly.
  • The meeting concluded that the GCMD instrument list is very comprehensive for satellite platform instruments but less so for marine instruments. The BODC list is good for marine instruments but has less granularity than GCMD.
  • The meeting therefore recommended using either of these two depending on the domain. The meeting also requested GCMD to consider a mapping between the GCMD and BODC.
