The Edukoppeling Transaction Standard, which standardises the logistics for data exchange in the education sector, has been in existence for several years. The standard is increasingly being used for exchanges within education where higher reliability is required (for example, when exchanging personal data), but certainly not everywhere yet. As a result, parties involved in data exchanges in multiple chains have to deal with different agreements and the security regulations that apply to them. This sometimes leads to interoperability problems for systems that have to deal with multiple data exchanges. At the meeting of the Standardisation Council on 25 April 2019, it was decided to set up a working group on ‘Uniform security regulations’.
