European Network – IDAN

CASD is member of the project IDAN – International Data Access Network). The Network is a collaboration between 6 Research Data Centers (RDCs) from Germany, France, the Netherlands and the United Kingdom in order to facilitate controlled data access for research purposes.

The purpose of this Network is to allow researchers to work remotely on one of the Partner’s data from any site of these RDCs. Access points of all partners are being progressively implemented at each site in a dedicated room (safe room) that meets the required security standards.

More information on the project is available on the IDAN website.

Access to partner’s data from CASD

CASD has set up a safe Room at his premises in Palaiseau. Three access points are currently installed in this room. They are:

  • For IAB data in Germany
  • For CBS Data in the Netherlands
  • A SD-Box for accessing CASD data

Whether you are a CASD user or not, you can ask to access IAB and CBS data following the necessary procedures from being certified by these centers to booking the room in Palaiseau by contacting CASD.

CASD is in charge of the cost of the access points according to the terms of the agreement with IAB and CBS (each data access cost depends on the center). You should note that the access is not through the CASD SD-Box but through equipment provided by IAB and CBS and installed for this purpose in our premises.

Before your first visit, you must imperatively have read the indications described in the following instructions guide: Guidelines for On-Site Use and Remote Date Access.

When using the safe room, it is strictly forbidden:

  • To use laptops, stocking or image recording devices (ex: camera, mobile phone…)
  • To communicate via telephone, email or SMS
  • To take notes

The German detailed data can be consulted at CASD premises; however, it is possible to modify your work from your place of work via the application JoSua. In order to optimize your time of visit, your files should be imperatively sent via JoSua 3 working days before your visit so you can have access once you arrive on site.

In order to facilitate your research, a table that summarizes potential comparisons of German and French data is available.

Access to CASD through the partners’ centers

SD-box allowing access to CASD data are installed on 4 partners’ sites. The installation of SD-box on these sites facilitates leading project of researchers using several partners’ data including that of CASD.
It also facilitates teamwork between researchers residing in different countries without being forced to move.
