Going Dutch:

The Netherlands National Oceanographic Data Committee

Taco de Bruin

Chair - National Oceanographic Data Committee (NODC)

NIOZ Royal Netherlands Institute for Sea Research

MEDIN Meeting 20090630


Slide2 l.jpg

  • Why a NODC – History of the NL-NODC

  • Conclusions from a workshop on oceanographic data management in The Netherlands in 1995:

  • Well organized at government agencies (RIKZ, Hydrographic Service, etc)

  • Complete lack of data management in academic community (research institutes, universities)

  • Largely dispersed within The Netherlands

  • No national policy or vision

  • No distinct representation towards outside world (national or international)

  • Lack of quarantees for preservation of data

  • No uniform data exchange format

  • Solutions:

  • Foundation of Data Management Group (DMG) at NIOZ in 1997 (to serve the academic community)

  • Foundation of NODC in 1997

MEDIN Meeting 20090630


Slide3 l.jpg

  • National Oceanographic Data Committee (NODC)

  • Committee – no centre

  • Based on Memorandum of Understanding (MoU) (1997-)

MEDIN Meeting 20090630


Slide4 l.jpg

  • National Oceanographic Data Committee (NODC)

  • Very interesting mix of government agencies (4), research institutes (2) and privatized, former government agencies (2)

  • Government agencies have specific tasks, limited to territory and EEZ of the Kingdom of The Netherlands, Netherlands Antilles and Aruba.

  • Other NODC Partners may operate all over the world

  • Data from all disciplines: Coastal research, bathymetry, geology, biology, ecology, physical oceanography, marine meteorology, etc, etc.

  • Many different data types

  • Broad expertise among Partner institutes

  • Flexible, efficient


Slide5 l.jpg

  • NODCObjectives (from MoU):

  • 1) to further data management and the delivery of quality data to a broad user group

  • 2) to lower thresholds and barriers (organizational, technical, financial) for data exchange

  • - obligation to conduct data management at institutional level

MEDIN Meeting 20090630

  • Early achievements and the role as national platform

  • NODC website with national overviews of:

  • - Datasets (in international EDMED format)

  • - Projects (in international EDMERP format) - Planned research cruises - ‘Grey’ literature - Individual measurements in Common Data Index (CDI) format (from EU-SeaSearch project)

MEDIN Meeting 20090630


Slide8 l.jpg

  • The NL-NODC is the national platform for oceano-graphic data management

  • Representing The Netherlands in international organizations and projects: - IODE - ICES (WGMDM and WGDIM) - EU-projects and initiatives as Sea-Search, SeaDataNet, EMODNET

  • The Dutch approach has been noticed internationally: - Australia: AODC-JF - United Kingdom - Italy - Portugal - France - Poland - Norway

NODC Data Policy: management

“5. Exchange and availability of data.

All oceanographic data such as defined in section 4 are in principle available and accessible for use and this free of charge.

In this connection a number of restrictions are to be complied with:

5.1 The data supplier is to be the rightful owner of the data.

5.2 The data supplier keeps the copy rights and remains owner of the data

5.3 The data supplier accepts no liability for the (consequences) of the use of the data supplied.

5.4 When data are used, e.g. for publication in any form, sources are to be quoted.”

Slide11 l.jpg

  • NODC: Organizational structure for data exchange: management

  • MoU

  • Data Policy

  • No uniform DATA ACCESS:

  • Data access should be key activity!!!!!!

  • No technical infrastructure for data exchange:

  • Different RDBMS

  • Different formats

  • Some databases online, others are not

Slide14 l.jpg

  • Situation of data exchange within NL-NODC a couple of years ago:

  • Online accessibility and availability of data

  • Waterbase (RIKZ)

  • CODIS (NIOZ)

  • KODAC (KNMI)

  • Watermarkt (RIKZ + many other partner institutes)

  • HYDRA (KNMI)

  • COREBASE (NIOZ)

  • DINO (TNO- B&O)

  • Getij.nl (RIKZ)

  • Waterstat.nl (RIKZ)

  • many more …..

  • - user had no overview of data availability- user had to do all format conversions and syntheses

MEDIN Meeting 20090630


Slide15 l.jpg

  • National infrastructure for access to oceanographic and ago:marine data and information:

  • NODC-i

  • Objectives of the project:

  • central index of all data in the partner databases

  • transparent access via Internet to the partner databases (fully distributed system)

  • Project:

  • February 2005 – December 2008 ( 2 phases)

  • 1 M Euro (500k from Bsik – Ruimte voor Geo-Informatie (RGI))

  • SeaDataNet technology

Slide20 l.jpg

The NODC web site is the Dutch node in the SeaDataNet network, linking the Dutch partner databases directly to the SeaDataNet infrastructure

MEDIN Meeting 20090630


Slide21 l.jpg

  • As a result from the NODC network, linking the Dutch partner databases directly to the SeaDataNet infrastructurei-project:

  • NIOZ was the very first institute in Europe to fully comply to SeaDataNet requirements

  • NODC is the very first node in Europe to become a fully functional node in the SeaDataNet Transnational Access network

MEDIN Meeting 20090630


Slide22 l.jpg

  • As a result from the NODC network, linking the Dutch partner databases directly to the SeaDataNet infrastructurei-project:

  • New MoU – needed to be renewed and rephrased, signed April 9

  • New membership – fisheries research institute (IMARES)

  • New data policy - external - differences in funding structure may cause problems: government and research institutes: public money – public access some organizations have to create revenue out of the data

  • New commitment - by partners (MoU signed by directors and discussed within management teams) - by outside world: NWO (national funding agency) now requires data to be delivered using NODC infrastructure and standards

MEDIN Meeting 20090630


Slide23 l.jpg

  • Pros and Cons of a Committee: network, linking the Dutch partner databases directly to the SeaDataNet infrastructure

  • National platform – Large pool of subject experts

  • No legal entity – both pro and con

  • Very limited financial resources

  • Lack of corporate feeling

MEDIN Meeting 20090630


Slide24 l.jpg

  • COMMUNICATION network, linking the Dutch partner databases directly to the SeaDataNet infrastructure:

  • Directors / management

  • Institutes / colleagues in other departments

  • Prevent re-inventing the wheel: Developments elsewhere which are in fact one step back

  • Advertize the infrastructure

MEDIN Meeting 20090630


Slide25 l.jpg

Meeting original objectives? network, linking the Dutch partner databases directly to the SeaDataNet infrastructure

1) to further data management All organizations convinced and active

2) the delivery of quality data to a broad user group All organizations consider this part of their tasks

3) to lower thresholds and barriers - organizational MoU signed by directors - technical NODCi infrastructure - financial MoU and Data Policy: free data exchange

4) % data availability ????? In principle 100%, in practice ??????

MEDIN Meeting 20090630


Slide26 l.jpg

Reasons to join the NL-NODC network, linking the Dutch partner databases directly to the SeaDataNet infrastructure

1) Need of data to perform own task NODC is platform for access to data from other partners

2) Make data available Data requests can now be handled by NODCi/SeaDataNet infrastructure – greater efficiency

3) NODCi/SeaDataNet infrastructure is ready for INSPIRE requirements and can directly be used for EMODNET projects (probably also for other national obligations, such as OSPAR)

4) NODC facilitates cooperation in national and European projects

5) No need to develop infrastructure and policies on your own and thus re-invent the wheel

6) Efficient to be able to act on behalf of a larger group in Europe
