1. Koninklijk Nederlands Instituut voor ZeeonderzoekRoyal Netherlands Institute for Sea Research 1 NIOZ is part of the Netherlands Organisation for Scientific Research (NWO) The Antarctic Master Directory: some thoughts and reflections

2. Koninklijk Nederlands Instituut voor ZeeonderzoekRoyal Netherlands Institute for Sea Research 2 NIOZ is part of the Netherlands Organisation for Scientific Research (NWO) Within oceanographic data management much experience with data set description formats: DIF - Used by GCMD: AMD, Ocean Sciences EDMED - European Directory of Marine and Environmental Data - SeaDataNet format - Based on DIF MEDI - IODE format - Identical to DIF - Hardly used

3. Koninklijk Nederlands Instituut voor ZeeonderzoekRoyal Netherlands Institute for Sea Research 3 NIOZ is part of the Netherlands Organisation for Scientific Research (NWO) Within oceanographic data management much experience with data set description formats: CSR - Cruise Summary Report - Format to describe activities during a cruise

4. Koninklijk Nederlands Instituut voor ZeeonderzoekRoyal Netherlands Institute for Sea Research 4 NIOZ is part of the Netherlands Organisation for Scientific Research (NWO) Data Managers perspective: Data set description formats are an excellent tool to get an overview of data holdings: - Necessary first step - Forces people to work in structured way - Parent – children DIFs - Ira van den Broek (IPY.NL Data Coordinator) is increasing number of Dutch DIFs in rapid pace

5. Koninklijk Nederlands Instituut voor ZeeonderzoekRoyal Netherlands Institute for Sea Research 5 NIOZ is part of the Netherlands Organisation for Scientific Research (NWO) Data Managers perspective: Issue: - Some ambiguity in filling out certain fields - Definite need to agree within SCADM on standard way of filling out fields

6. Koninklijk Nederlands Instituut voor ZeeonderzoekRoyal Netherlands Institute for Sea Research 6 NIOZ is part of the Netherlands Organisation for Scientific Research (NWO) Data Users perspective: Issues: - According to AMD statistics there are users from NL - Never heard of any scientist in NL using the AMD - Need for massive PR campaign by NADCs, SCADM, SCAR

7. Koninklijk Nederlands Instituut voor ZeeonderzoekRoyal Netherlands Institute for Sea Research 7 NIOZ is part of the Netherlands Organisation for Scientific Research (NWO) Data Users perspective: Needs: - DIFs linked to online available data - Linking DIFs to get integrated overview of data instead of list of DIFs - Solution (or agreement) to the granularity problem

8. Koninklijk Nederlands Instituut voor ZeeonderzoekRoyal Netherlands Institute for Sea Research 8 NIOZ is part of the Netherlands Organisation for Scientific Research (NWO) One DIF – no data

9. Koninklijk Nederlands Instituut voor ZeeonderzoekRoyal Netherlands Institute for Sea Research 9 NIOZ is part of the Netherlands Organisation for Scientific Research (NWO) Two DIFs – more work

10. Koninklijk Nederlands Instituut voor ZeeonderzoekRoyal Netherlands Institute for Sea Research 10 NIOZ is part of the Netherlands Organisation for Scientific Research (NWO) One DIF for each data point – a lot more work?

11. Koninklijk Nederlands Instituut voor ZeeonderzoekRoyal Netherlands Institute for Sea Research 11 NIOZ is part of the Netherlands Organisation for Scientific Research (NWO) Data Managers en Data Users perspective: Needs: - GCMD and SCADM need to make next step from data set descriptions to individual data point descriptions - Data point descriptions should provide access to data - Example is Common Data Index (CDI) approach within SeaDataNet – see presentation tomorrow
