Open Data has been considered as a key to scientific innovations. These openly licensed data-sets can be accessed, used, rebuild, and shared by anyone and anywhere. Mostly, Open Data is discussed in relation to its production, storage, licensing and accessibility, but less often - in relation to its practical subsequent uses, e.g. as an educational resource. In general, Open Data can be used as an open educational resource to develop transversal skills among school students. This paper presents an Enterprise Architecture Oriented Requirements Engineering (EAORE) approach for Open Data usage as an educational resource in Danish public schools. The aim of this research work is to identify requirements of Danish public schools for the development of an Open Data interface. The EAORE approach represents how Enterprise Architecture (EA) models guide overall Requirements Engineering (RE) process for Open Data usage in Danish public schools.
