BMDC Data Policy

Version 3.5 - April 2026

Most of the data available at BMDC pertain to environmental matters. They fall, therefore, under the scope of the UN Convention On Access To Information, Public Participation In Decision-Making And Access To Justice In Environmental Matters (aka the "Aarhus Convention") which provides that "public authorities, in response to a request for environmental information, make such information available to the public". This convention has been implemented in both European and Belgian legislations (Law of December 17th, 2002).

Another reference frame with which BMDC wants to comply is the "IOC Data Policy and Terms of Use (2023)" as adopted during the 32nd Session of the IOC Assembly (https://legacy.iode.org/legacy.iode.org/index9edd.html?option=com_content&view=article&id=51&Itemid=95 ). This Policy establishes as a basic principle (for IOC programmes) or goal to reach the "timely, free and unrestricted exchange of or access to" oceanographic data. It recommends that member states and their ocean practitioners share their data, while also recommending the use of licenses to ensure that the work of the scientist/data provider is recognized.

As such, datasets obtained via the search interface of BMDC, receive a CC-BY license. Data consumers must properly and clearly cite both the data owners (RBINS and any other) and authors.

BMDC is bound the Open Data Directive (EU) 2019/1024 (ODD) and the Belgian implementation of it to render data to be as “open as possible and as closed as strictly necessary”. As far as possible, our data are therefore made freely available to the public through our website[1].

BMDC recognizes the human efforts needed to collect and interpret these data. Scientists, for instance, spend a long time setting up experiments, testing them, defining a methodology, performing the sampling and analyzing the results. Their work is most often measured in terms of their scientific publications. Scientific publishing is a long process, from the field and lab works to the final version of the paper. It is therefore usual that data be covered by an embargo, allowing the author of the data to have sufficient time to exploit them.

The duration of the embargo is set in an agreement between the BMDC and the author of the data. A common duration is two years after the samples are collected or analysed.

Such an embargo doesn't apply to data collected by or for public authorities as part of public-funded monitoring programmes. In such cases, free access to our data is granted as soon as data submitted to the BMDC have passed our validation procedures.

"Free access" must be strictly understood within the context of our "Data Access Rules":

  • access to our data is granted to individuals; true information must be given when registering and a given username and password may not be used by anyone else than the registered person;

  • our data are covered by intellectual property rights;

  • data download is only permitted for personal use by granted users;

  • use of our data for scientific research is permitted, provided any publication making use of these data makes explicit reference to their Author and to the source;

  • no publication of our data in any electronic form is allowed without prior explicit agreement with the Royal Belgian Institute of Natural Sciences, represented by the Head of the BMDC, and with the Author of the data;

  • no direct or indirect commercial use of our data is allowed without prior explicit agreement with the Royal Belgian Institute of Natural Sciences, represented by the Head of the BMDC, and with the Author of the data;

It is the user's onus to obey these rules. The Belgian State, represented either by the Royal Belgian Institute of Natural Sciences or by the Federal Science Policy, reserves the right to take any action, even in court, when there is evidence that these rules are infringed.
