The issues that were explored relate to questions about national policies and frameworks for the design of a cross-university (national) infrastructure for the dissemination of OER (macro-level) issues related to the provision of OER in higher education institutions, e.g. technical and support infrastructure, professional development, and quality assurance (meso level). Also included were questions about the creation and use of OER in higher education teaching and learning, and concepts for sharing them among faculty members (micro-level).

Cross-comparative analysis of the country studies are also published in a series of journal articles: Open Praxis (macro-level), Open Education Studies (meso-level), and Research and Practice in Technology Enhanced Learning (micro-level) - see Marín et al. (2020), Marín et al. (2022a), and Marín et al. (2022b).
