Data policy at VLIZ

WDS Data Policy   There will be full and open exchange of data, metadata and products shared within WDS, … All shared data, metadata and products being free of charge or no more than cost of reproduction will be encouraged for research and education.

IOC Oceanographic Data Exchange Policy

Member States shall provide timely, free and unrestricted access to all data, associated metadata and products generated under the auspices of IOC programmes. Member States are encouraged to provide timely, free and unrestricted access to relevant data and associated metadata from non-IOC programmes …. for non-commercial use by the research and education communities, provided that any products or results of such use shall be published in the open literature without delay or restriction.

Data policy at VLIZ

(under development)

VLIZ advocates free data exchange and supports the IOC Oceanographic Data Exchange Policy. Wherever possible and relevant, the data from the databases will be made available online through the Internet. Naturally, restrictions may apply, as a result of which we cannot offer unlimited access. This is for example the case for data of which VLIZ is not the primary source: in this case the data exchange policy of the originator of the data will apply.

data citation & DOI linking will be made possible:

Different versions of a dataset each having their own citation (according to Data Cite) & DOI link.DOI is referring to different versions of the data on the MDA.

EMODnet Central Portal – Use cases

• Highlight added value of bringing thematic data together

• Use Cases will be used as a roadmap for developing the Portal

• Generate functional requirements of portal

EMODnet Central Portal – Use case 1

• Be able to get access to the data via WFS (GetFeature)

• Perform queries over WFS• Return output in different formats (list of

features per coordinate point, list of points or area, Indexes etc.)

Use Case 1: Query data products simultaneously

Retrieve Data from specified coordinates at a given time or for a time interval

Marine Region (ICES, Protected Area)

EMODnet– marine data ingestion

• Up to now the focus of EMODnet has been distribution of data but some attention now needs to be devoted to ingestion of data. This requires a facility that

– provides instructions – ingests the data– checks them – directs them to the appropriate repository for stewardship and dissemination

• Facility for data ingestion, available through www.emodnet.eu– Tool to check (QC, standardization, dataformat checks) can be built in parallel EMODnet service tool – Tool needs to redirect data to appropriate repositories for archiving (WDS, NODC) – Tool needs to allow the creation of a datacitation (URI e.a.DOI) and possibly linked data publication– Tool should prepare data for integration into EMODnet thematic products, other integrating datasystems and common data

catalogues (GEBCO, OBIS, CDI…)

• Uniform way for data citations – ‘Introduction to Digital Citation – Towards an ICES policy on Data Citation’ – currently in prep
